Overview  
Audience  
Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1  
(SIP), Cisco Unified IP Phones 7970G/7971G-GE provides the information you  
need to understand, install, configure, manage, and troubleshoot the phones in the  
Cisco Unified IP Phone 7970 series on a Voice-over-IP (VoIP) network.  
Because of the complexity of an IP telephony network, this guide does not provide  
complete and detailed information for procedures that you need to perform in  
Cisco Unified CallManager or other network devices. See the “Related  
Documentation” section on page xvii.  
Network engineers, system administrators, or telecom engineers should review  
this guide to learn the steps required to properly set up the Cisco Unified IP Phone  
7970 Series on the network.  
The tasks described are administration-level tasks and are not intended for  
end-users of the phones. Many of the tasks involve configuring network settings  
and affect the phone’s ability to function in the network.  
Because of the close interaction between the Cisco Unified IP Phone and  
Cisco Unified CallManager, many of the tasks in this manual require familiarity  
with Cisco Unified CallManager.

Submitting a Service Request  
Using the online TAC Service Request Tool is the fastest way to open S3 and S4  
service requests. (S3 and S4 service requests are those in which your network is  
minimally impaired or for which you require product information.) After you  
describe your situation, the TAC Service Request Tool provides recommended  
solutions. If your issue is not resolved using the recommended resources, your  
service request is assigned to a Cisco engineer. The TAC Service Request Tool is  
located at this URL:  
For S1 or S2 service requests, or if you do not have Internet access, contact the  
Cisco TAC by telephone. (S1 or S2 service requests are those in which your  
production network is down or severely degraded.) Cisco engineers are assigned  
immediately to S1 and S2 service requests to help keep your business operations  
running smoothly.  
To open a service request by telephone, use one of the following numbers:  
Asia-Pacific: +61 2 8446 7411  
Australia: 1 800 805 227  
EMEA: +32 2 704 55 55  
USA: 1 800 553 2447

Definitions of Service Request Severity  
To ensure that all service requests are reported in a standard format, Cisco has  
established severity definitions.  
Severity 1 (S1)—An existing network is “down” or there is a critical impact to  
your business operations. You and Cisco will commit all necessary resources  
around the clock to resolve the situation.  
Severity 2 (S2)—Operation of an existing network is severely degraded, or  
significant aspects of your business operations are negatively affected by  
inadequate performance of Cisco products. You and Cisco will commit full-time  
resources during normal business hours to resolve the situation.

Preface  
Obtaining Additional Publications and Information  
Severity 3 (S3)—Operational performance of the network is impaired while most  
business operations remain functional. You and Cisco will commit resources  
during normal business hours to restore service to satisfactory levels.  
Severity 4 (S4)—You require information or assistance with Cisco product  
capabilities, installation, or configuration. There is little or no effect on your  
business operations.

An Overview of the Cisco  
Unified IP Phone  
The Cisco Unified IP Phones 7970G/7971G-GE are full-featured telephones that  
provide voice communication over an Internet Protocol (IP) network. They  
function much like digital business telephones, allowing you to place and receive  
phone calls and to access features such as mute, hold, transfer, speed dial, call  
forward, and more. In addition, because Cisco Unified IP Phones are connected  
to your data network, they offer enhanced productivity features, including access  
to network information, XML applications, and customizeable features. The  
phones also support security features that include file authentication, device  
authentication, signaling encryption, and media encryption.  
The Cisco Unified IP Phones 7970G/7971G-GE provide a color touchscreen,  
managed. The phone supports G.711aLaw, G.711uLaw, G.729, G.729a, G.729b,

establish, maintain, and terminate calls between two or more endpoints.  
Like other VoIP protocols, SIP is designed to address the functions of signaling  
and session management within a packet telephony network. Signaling allows call  
information to be carried across network boundaries. Session management  
provides the ability to control the attributes of an end-to-end call.

Feature Overview  
Cisco Unified IP Phones provide traditional telephony functionality, such as call  
forwarding and transferring, redialing, speed dialing, conference calling, and  
voice messaging system access. Cisco Unified IP phones also provide a variety of  
other features. For an overview of the telephony features that the  
Cisco Unified IP Phone supports, see the “Telephony Features Available for the  
Phone” section on page 5-2.  
As with other network devices, you must configure Cisco Unified IP Phones to  
prepare them to access Cisco Unified CallManager and the rest of the IP network.  
By using DHCP, you have fewer settings to configure on a phone, but can  
manually configure an IP address, TFTP server, and subnet mask if your network  
requires it. For instructions on configuring the network settings on the  
Cisco Unified IP Phones, see Chapter 4, “Configuring Settings on the  
Cisco Unified IP Phone.”  
The Cisco Unified IP Phone can interact with other services and devices on your  
IP network to provide enhanced functionality. For example, you can integrate the  
Cisco Unified IP Phones with the corporate Lightweight Directory Access  
Protocol 3 (LDAP3) standard directory to enable users to search for co-workers  
contact information directly from their IP phones. You can also use XML to  
enable users to access information such as weather, stocks, quote of the day, and

Providing Users with Feature Information  
If you are a system administrator, you are likely the primary source of information  
for Cisco Unified IP Phone users in your network or company. To ensure that you  
distribute the most current feature and procedural information, familiarize  
yourself with Cisco Unified IP Phone documentation. Make sure to visit the  
Cisco Unified IP Phone web site:  
From this site, you can view various user guides. For complete ordering  
information, see the “Obtaining Documentation” section on page -Boilerplate 1.  
In addition to providing users with documentation, it is important to inform them  
about available Cisco Unified IP Phone features—including features specific to  
your company or network—and about how to access and customize those  
features, if appropriate.  
For a summary of some of the key information that phone users need their system  
administrators to provide, see Appendix A, “Providing Information to Users Via

Understanding Security Features for Cisco Unified IP  
Phones  
Implementing security in the Cisco Unified CallManager system prevents identity  
theft of the phone and Cisco Unified CallManager server, prevents data  
tampering, and prevents call signaling and media stream tampering.  
To alleviate these threats, the Cisco IP telephony network establishes and  
maintains authenticated and encrypted communication streams between a phone  
and the server, digitally signs files before they are transferred to a phone, and  
encrypts media streams and call signaling between Cisco Unified IP phones.  
The Cisco Unified IP Phones 7970G/7971G-GE (SIP) use the SIP Phone security  
profile, which defines whether the device is nonsecure, authenticated, or  
encrypted. For information on applying the security profile to the phone, refer to  
the Cisco Unified CallManager Security Guide.  
If you configure security-related settings in Cisco Unified CallManager  
Administration, the phone configuration file will contain sensitive information.  
To ensure the privacy of a configuration file, you must configure it for encryption.  
For detailed information, refer to the “Configuring Encrypted Phone  
Configuration Files” chapter in Cisco Unified CallManager Security Guide.  
Table 1-2 shows where you can find additional information about security in this  
and other documents.

Table 1-3  
Overview of Security Features  
Feature  
Description  
Image authentication  
Signed binary files (with the extension .sbn) prevent tampering with  
the firmware image before it is loaded on a phone. Tampering with  
the image causes a phone to fail the authentication process and  
reject the new image.  
Customer-site certificate  
installation  
Each Cisco Unified IP Phone requires a unique certificate for device  
authentication. Phones include a manufacturing installed  
certificate, but for additional security, you can specify in Cisco  
Unified CallManager Administration that a certificate be installed  
by using the CAPF. Alternatively, you can initiate the installation  
of an LSC from the Security Configuration menu on the phone.  
Device authentication  
Occurs between the Cisco Unified CallManager server and the  
phone when each entity accepts the certificate of the other entity.  
Determines whether a secure connection between the phone and a  
Cisco Unified CallManager should occur, and, if necessary, creates  
a secure signaling path between the entities using TLS protocol.  
Cisco Unified CallManager will not register phones unless they can  
be authenticated by the Cisco Unified CallManager.  
File authentication  
Validates digitally-signed files that the phone downloads. The  
phone validates the signature to make sure that file tampering did  
not occur after the file creation. Files that fail authentication are not  
written to Flash memory on the phone. The phone rejects such files  
without further processing.  
Signaling Authentication  
Uses the TLS protocol to validate that no tampering has occurred to  
signaling packets during transmission.  
Manufacturing installed  
certificate  
Each Cisco Unified IP Phone contains a unique manufacturing  
installed certificate (MIC), which is used for device authentication.  
The MIC is a permanent unique proof of identity for the phone, and  
allows Cisco Unified CallManager to authenticate the phone.  
Media encryption  
Uses SRTP to ensure that the media streams between supported  
devices proves secure and that only the intended device receives  
and reads the data. Includes creating a media master key pair for the  
devices, delivering the keys to the devices, and securing the  
delivery of the keys while the keys are in transport.

Feature  
Description  
Signaling Encryption  
Ensures that all SIP signaling messages that are sent between the  
device and the Cisco Unified CallManager server are encrypted.  
CAPF (Certificate Authority  
Proxy Function)  
Implements parts of the certificate generation procedure that are too  
processing-intensive for the phone, and it interacts with the phone  
for key generation and certificate installation. The CAPF can be  
configured to request certificates from customer-specified  
certificate authorities on behalf of the phone, or it can be configured  
to generate certificates locally.  
Security Profiles  
Defines whether the phone is nonsecure, authenticated, or  
encrypted.  
Encrypted Configuration files  
Optional disabling of the web  
Enables privacy of phone configuration files.  
You can prevent access to a phone’s web page, which displays a  
server functionality for a phone variety of operational statistics for the phone.

802.1X Authentication  
The Cisco Unified IP Phone can use 802.1X authentication to  
request and gain access to the network. See the “Supporting 802.1X  
Authentication on Cisco Unified IP Phones” section on page 1-18  
for more information.

Identifying Encrypted and Authenticated Phone Calls  
When security is implemented for a phone, you can identify authenticated or  
encrypted phone calls by icons on the LCD screen on the phone.  
In an authenticated call, all devices participating in the establishment of the call  
are authenticated by the Cisco Unified CallManager. When a call in progress is  
authenticated end-to-end, the call progress icon to the right of the call duration  
timer in the phone LCD screen changes to the following icon:

Understanding Security Features for Cisco Unified IP Phones  
In an encrypted call, all devices participating in the establishment of the call are  
authenticated by the Cisco Unified CallManager. In addition, call signaling and  
media streams are encrypted. An encrypted call offers the highest level of  
security, providing integrity and privacy to the call. When a call in progress is  
being encrypted, the call progress icon to the right of the call duration timer in the  
phone LCD screen changes to the following icon:  
Note  
If the call is routed through non-IP call legs, for example, H.323 or PSTN, the call  
will be nonsecure even though it is encrypted within the IP network and has a lock  
icon associated with it.

Overview  
Cisco Unified IP phones and Cisco Catalyst switches have traditionally used  
Cisco Discovery Protocol (CDP) to identify each other and determine parameters  
such as VLAN allocation and inline power requirements. However, CDP is not  
used to identify any locally attached PCs, therefore Cisco Unified IP Phones  
provide an EAPOL pass-through mechanism, whereby a PC locally attached to  
the IP phone, may pass through EAPOL messages to the 802.1X authenticator in

Chapter 1 An Overview of the Cisco Unified IP Phone  
Understanding Security Features for Cisco Unified IP Phones  
the LAN switch. This prevents the IP phone from having to act as the  
authenticator, yet allows the LAN switch to authenticate a data end point prior to  
accessing the network.  
In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP  
Phones provide a proxy EAPOL-Logoff mechanism. In the event that the locally  
attached PC is disconnected from the IP phone, the LAN switch would not see the  
physical link fail, because the link between the LAN switch and the IP phone is  
maintained. To avoid compromising network integrity, the IP phone sends an  
EAPOL-Logoff message to the switch, on behalf of the downstream PC, which  
triggers the LAN switch to clear the authentication entry for the downstream PC.  
The Cisco Unified IP phones also contain an 802.1X supplicant, in addition to the  
EAPOL pass-through mechanism. This supplicant allows network administrators  
to control the connectivity of IP phones to the LAN switch ports. The initial  
release of the IP phone 802.1X supplicant implements the EAP-MD5 option for  
802.1X authentication.  
Required Network Components  
Support for 802.1X authentication on Cisco Unified IP Phones requires several  
components, including:  
Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which  
initiates the request to access the network.  
Cisco Secure Access Control Server (ACS) (or other third-party  
authentication server)—The authentication server and the phone must both be  
configured with a shared secret that is used to authenticate the phone.  
Cisco Catalyst Switch (or other third-party switch)—The switch must support  
802.1X so it can act as the authenticator and pass the messages between the  
phone and the authentication server. When the exchange is completed, the  
Best Practices—Requirements and Recommendations  
Enable 802.1X Authentication—If you want to use the 802.1X standard to  
authenticate Cisco Unified IP Phones, be sure that you have properly  
configured the other components before enabling it on the phone. See the  
“802.1X Authentication and Status” section on page 4-42 for more  
information.

OL-11524-01

Chapter 1 An Overview of the Cisco Unified IP Phone  
Understanding Security Features for Cisco Unified IP Phones  
Configure PC Port—The 802.1X standard does not take into account the use  
of VLANs and thus recommends that only a single device should be  
authenticated to a specific switch port. However, some switches (including  
Cisco Catalyst switches) support multi-domain authentication. The switch  
configuration determines whether you can connect a PC to the phone’s PC  
port.  
Enabled—If you are using a switch that supports multi-domain  
authentication, you can enable the PC port and connect a PC to it. In this  
case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor  
the authentication exchanges between the switch and the attached PC.  
For more information about IEEE 802.1X support on the Cisco Catalyst  
switches, refer to the Cisco Catalyst switch configuration guides at:  
http://www.cisco.com/en/US/products/hw/switches/tsd_products_suppo  
rt_category_home.html  
Disabled—If the switch does not support multiple 802.1X-compliant  
devices on the same port, you should disable the PC Port when 802.1X  
authentication is enabled. See the “Security Configuration Menu”  
section on page 4-33 for more information. If you do not disable this port  
and subsequently attempt to attach a PC to it, the switch will deny  
network access to both the phone and the PC.  
Configure Voice VLAN—Because the 802.1X standard does not account for  
VLANs, you should configure this setting based on the switch support:  
Enabled—If you are using a switch that supports multi-domain  
authentication, you can continue to use the voice VLAN.  
Disabled—If the switch does not support multi-domain authentication,  
disable the Voice VLAN and consider assigning the port to the native  
VLAN. See the “Security Configuration Menu” section on page 4-33 for  
more information.  
Enter MD5 Shared Secret—If you disable 802.1X authentication or perform  
a factory reset on the phone, the previously configured MD5 shared secret is  
deleted. See the “802.1X Authentication and Status” section on page 4-42 for  
more information.

Security Restrictions  
A user cannot barge into an encrypted call if the phone that is used to barge is not  
configured for encryption. When barge fails in this case, a reorder tone (fast busy  
tone) plays on the phone on which the user initiated the barge.  
If the initiator phone is configured for encryption, the barge initiator can barge  
into an authenticated or nonsecure call from the encrypted phone. After the barge  
occurs, Cisco Unified CallManager classifies the call as nonsecure.  
If the initiator phone is configured for encryption, the barge initiator can barge  
into an encrypted call, and the phone indicates that the call is encrypted.  
A user can barge into an authenticated call, even if the phone that is used to barge  
is nonsecure. The authentication icon continues to appear on the authenticated  
devices in the call, even if the initiator phone does not support security.

Understanding How the Cisco Unified IP Phone Interacts with the  
VLAN  
The Cisco Unified IP Phones 7970G/7971G-GE have an internal Ethernet switch,  
that enable forwarding of packets to the phone, and to the access port and the  
network port on the back of the phone.  
If a computer is connected to the access port, the computer and the phone share  
the same physical link to the switch and share the same port on the switch. This  
shared physical link has the following implications for the VLAN configuration  
on the network:  
The current VLANs might be configured on an IP subnet basis. However,  
additional IP address might not be available to assign the phone to the same  
subnet as other devices connect to the same port.

Providing Power to the Phone  
Data traffic present on the data/native VLAN may reduce the quality of  
Voice-over-IP traffic.  
Network security may indicate a need to isolate the VLAN voice traffic from  
the VLAN data traffic.  
You can resolve these issues by isolating the voice traffic onto a separate VLAN.  
The switch port that the phone is connected to would be configured to have  
separate VLANs for carrying:  
Voice traffic to and from the IP phone (auxiliary VLAN, on the  
Cisco Catalyst 6000 series, for example)  
Data traffic to and from the PC connected to the switch through the access  
port of the IP phone (native VLAN)  
Isolating the phones on a separate, auxiliary VLAN improves the quality of the  
voice traffic and allows a large number of phones to be added to an existing

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network  
Understanding Phone Configuration Files  
Understanding Phone Configuration Files  
Configuration files for a phone are stored on the TFTP server and define  
parameters for connecting to Cisco Unified CallManager. In general, any time  
you make a change in Cisco Unified CallManager that requires the phone to be  
reset, a change is made to the phone’s configuration file automatically.  
Configuration files also contain information about which image load the phone  
should be running. If this image load differs from the one currently loaded on a  
phone, the phone contacts the TFTP server to request the required load files.  
(These files are digitally signed to ensure the authenticity of the files’ source.)  
In addition, if the device security mode in the configuration file is set to  
Authenticated and the CTL file on the phone has a valid certificate for  
Cisco Unified CallManager, the phone establishes a TLS connection to  
Cisco Unified CallManager. Otherwise, the phone establishes a TCP connection.  
The transport protocol in the configuration file must also be set to TLS  
(corresponding to the transport type in the SIP Security Profile on Cisco Unified  
CallManager).  
Note  
If the device security mode in the configuration file is set to Authenticated or  
Encrypted, but the phone has not received a CTL file, the phone will continuously  
try to obtain a CTL file so that it can register securely.  
A phone requests a configuration file whenever it resets and registers with  
Cisco Unified CallManager.  
A phone accesses a default configuration file named XmlDefault.cnf.xml from the  
TFTP server when the following conditions exist:  
You have enabled auto-registration in Cisco Unified CallManager  
The phone has not been added to the Cisco Unified CallManager Database  
The phone is registering for the first time  
If auto registration is not enabled and the phone has not been added to the  
Cisco Unified CallManager Database, the phone registration request will be  
rejected. In this case, the phone will reset and attempt to register repeatedly.  
If the phone has registered before, the phone will access the configuration file  
named SEPmac_address.cnf.xml, where mac_address is the MAC address of the  
phone.

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network  
Understanding the Phone Startup Process  
For more information about how the phone interacts with the TFTP server, refer  
to the Cisco Unified CallManager System Guide, “Cisco TFTP” chapter.  
The TFTP server generates these SIP configuration files:  
SIP IP Phone:  
For unsigned and unencrypted files—SEP<mac>.cnf.xml  
For signed files—SEP<mac>.cnf.xml.sgn  
For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn  
Dial Plan—<dialplan>.xml  
Softkey Template—<softkey_template>.xml  
The filenames are derived from the MAC Address and Description fields in the  
Phone Configuration window of Cisco Unified CallManager Administration and  
the devicename field in the Cisco Unified CallManager database. The MAC  
address uniquely identifies the phone. For more information refer to the Cisco  
Unified CallManager Administration Guide.  
SIP Dial Rules  
For Cisco SIP Unified IP phones, the administrator uses dial rules to configure  
SIP phone dial plans. These dial plans must be associated with a SIP phone device  
to enable dial plans to be sent to the configuration file. If the administrator does  
not configure a SIP phone dial plan, the phone does not display any indication of  
a dial plan.  
For more information on configuring SIP dial rules, refer to the Cisco Unified  
CallManager Administration Guide.  
Understanding the Phone Startup Process  
When connecting to the VoIP network, the Cisco Unified IP Phone goes through  
a standard startup process, as described in Table 2-4. Depending on your specific  
network configuration, not all of these steps may occur on your  
Cisco Unified IP Phone.

phone initializes its software and hardware.  
3. Configuring VLAN. If the Cisco Unified IP Phone is connected to a  
Cisco switch, the switch next informs the phone of  
the voice VLAN defined on the switch port. The  
phone needs to know its VLAN membership  
before it can proceed with the Dynamic Host

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network  
Adding Phones to the Cisco Unified CallManager Database  
Adding Phones with Auto-Registration  
You can add phones with auto-registration without first gathering MAC addresses  
from the phones.  
Note  
Cisco recommends you use auto-registration to add less than 100 phones to your  
network. To add more than 100 phones to your network, use the Bulk  
Administration Tool (BAT). See the “Adding Phones with BAT” section on  
page 2-16.  
When auto-registration is enabled, Cisco Unified CallManager begins the  
automatic startup process to obtain a directory number. During auto-registration,  
Cisco Unified CallManager automatically assigns the next available sequential  
directory number to the phone.  
When you use this method, Cisco Unified CallManager automatically assigns  
directory numbers to new phones as they register with Cisco Unified  
CallManager.  
You can use auto-registration to quickly enter phones into the  
Cisco Unified CallManager database. You can then modify any settings, such as  
the directory numbers, from Cisco Unified CallManager. Additionally, you can  
move auto-registered phones to new locations and assign them to different device  
pools without affecting their directory numbers.  
Auto-registration is disabled by default.  
For information about enabling and configuring auto-registration, refer to Cisco  
Unified CallManager Administration Guide.  
Note  
When you configure the cluster for mixed mode through the Cisco CTL client,  
non-secure mode through the Cisco CTL client, auto-registration is automatically  
enabled.

Adding Phones to the Cisco Unified CallManager Database  
You can add phones with auto-registration and TAPS without first gathering  
MAC addresses from phones.  
Note  
Cisco recommends you use auto-registration and TAPS to add less than 100  
phones to your network. To add more than 100 phones to your network, use the  
Bulk Administration Tool (BAT). See the “Adding Phones with BAT” section on  
page 2-16.  
TAPS, the Tool for Auto-Registered Phones Support, works with the Bulk  
Administration Tool (BAT) to update phones that were already added to the  
Cisco Unified CallManager database with dummy MAC addresses. Use TAPS to  
update MAC addresses and download pre-defined configurations for phones.  
To implement TAPS, you or the end-user dial a TAPS directory number and  
follow voice prompts. When the process is complete, the phone will have  
downloaded its directory number and other settings, and the phone will be  
updated in Cisco Unified CallManager Administration with the correct MAC  
address.  
Auto-registration must be enabled in Cisco Unified CallManager Administration  
(System > Cisco CallManager) for TAPS to function.  
Note  
When you configure the cluster for mixed mode through the Cisco CTL client,  
auto-registration is automatically disabled. When you configure the cluster for  
enabled.

Understanding the Cisco Unified IP Phone 7970G/7971G-GE Components  
The Cisco Unified IP Phone 7970G/7971G-GE includes these components on the  
phone or as accessories for the phone:  
Network and Access Ports, page 3-5  
Handset, page 3-5  
Speakerphone, page 3-6  
Headset, page 3-6  
Network and Access Ports  
The back of the Cisco Unified IP Phone 7970G/7971G-GE includes these ports:  
Network port—Labeled 10/100 SW on the Cisco Unified IP Phone 7970G  
and 10/100/1000 SW on the Cisco Unified IP Phone 7971G-GE  
Access port—Labeled 10/100 PC on the Cisco Unified IP Phone 7970G and  
10/100/1000 PC on the Cisco Unified IP Phone 7971G-GE  
Each port supports 10/100 or 10/100/1000 Mbps half- or full-duplex connections  
to external devices. You can use either Category 3 or 5 cabling for 10-Mbps  
connections, but you must use Category 5 for 100 and 1000 Mbps connections.  
Use the SW network port to connect the phone to the network. You must use a  
straight-through cable on this port. The phone can also obtain inline power from  
a switch over this connection. See the “Providing Power to the Phone” section on  
page 2-4 for details.  
Use the PC access port to connect a network device, such as a computer, to the  
phone. You must use a straight-through cable on this port.  
Handset  
The handset is designed especially for use with a Cisco Unified IP Phone. It  
includes a light strip that indicates incoming calls and voice messages waiting.

Speakerphone  
By default, the speakerphone is enabled on Cisco Unified IP Phones  
7970G/7971G-GE.  
You can disable the speakerphone through the Cisco Unified CallManager  
Administration application. To do so, choose Device > Phone and locate the  
phone you want to modify. In the Phone Configuration web page for the phone,  
check the Disable Speakerphone check box.  
Headset  
Although Cisco Systems performs some internal testing of third-party headsets  
for use with the Cisco Unified IP Phones, Cisco does not certify or support  
products from headset or handset vendors. Because of the inherent environmental  
and hardware inconsistencies in the locations where Cisco Unified IP Phones are  
deployed, there is not a single “best” solution that is optimal for all environments.  
Cisco recommends that customers test the headsets that work best in their  
environment before deploying a large number of units in their network.  
In some instances, the mechanics or electronics of various headsets can cause  
remote parties to hear an echo of their own voice when they speak to  
Cisco Unified IP Phone users.  
Cisco Systems recommends the use of good quality headsets that are screened  
against unwanted radio frequency (RF) and audio frequency (AF) signals.  
Depending on the quality of headsets and their proximity to other devices such as  
cell phones and two-way radios, some audio noise may still occur.  
The primary reason that support of a headset would be inappropriate for an  
installation is the potential for an audible hum. This hum can either be heard by  
the remote party or by both the remote party and the Cisco Unified IP Phone user.  
Some potential humming or buzzing sounds can be caused by a range of outside  
sources, for example, electric lights, being near electric motors, large PC  
monitors. In some cases, a hum experienced by a user may be reduced or  
eliminated by using a local power cube (CP-PWR-CUBE-3). See the “Safety”  
section on page 3-3 for more information.

Chapter 3 Setting Up the Cisco Unified IP Phone  
Understanding the Cisco Unified IP Phone 7970G/7971G-GE Components  
Audio Quality Subjective to the User  
Beyond the physical, mechanical and technical performance, the audio portion of  
a headset must sound good to the user and the party on the far end. Sound is  
subjective and Cisco cannot guarantee the performance of any headsets or  
handsets, but some of the headsets and handsets on the sites listed below have  
been reported to perform well on Cisco Unified IP Phones.  
Nevertheless, it is ultimately still the customer’s responsibility to test this  
equipment in their own environment to determine suitable performance.  
For information about headsets, see:  
Connecting a Headset  
To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port  
on the back of the phone. Press the Headset button on the phone to place and  
answer calls using the headset.  
You can use the headset with all of the features on the Cisco Unified IP Phone,  
including the Volume and Mute buttons. Use these buttons to adjust the ear piece  
volume and to mute the speech path from the headset microphone.  
Disabling a Headset  
You can disable the headset through the Cisco Unified CallManager  
Administration application. If you do so, you also will disable the speakerphone.  
To disable the headset from Cisco Unified CallManager Administration, choose  
Device > Phone and locate the phone that you want to modify. In the Phone  
Configuration web page for the phone, check the Disable Speakerphone and  
Headset check box.

Chapter 3 Setting Up the Cisco Unified IP Phone  
Understanding the Cisco Unified IP Phone 7970G/7971G-GE Components  
Using External Devices with Your Cisco Unified IP Phone  
The following information applies when you use external devices with the  
Cisco Unified IP Phone:  
Cisco recommends the use of good quality external devices (speakers,  
microphones, and headsets) that are shielded (screened) against unwanted radio  
frequency (RF) and audio frequency (AF) signals.  
Depending on the quality of these devices and their proximity to other devices  
such as mobile phones or two-way radios, some audio noise may still occur. In  
these cases, Cisco recommends that you take one or more of the following actions:  
Move the external device away from the source of the RF or AF signals.  
Route the external device cables away from the source of the RF or AF  
signals.  
Use shielded cables for the external device, or use cables with a better shield  
and connector.  
Shorten the length of the external device cable.  
Apply ferrites or other such devices on the cables for the external device.  
Cisco cannot guarantee the performance of the system because Cisco has no  
control over the quality of external devices, cables, and connectors. The system  
will perform adequately when suitable devices are attached using good quality  
cables and connectors.  
Caution  
In European Union countries, use only external speakers, microphones, and  
headsets that are fully compliant with the EMC Directive [89/336/EC].

Configuring Corporate Directories and Personal Directories  
Configuring Corporate Directories  
Cisco Unified CallManager uses a Lightweight Directory Access Protocol  
(LDAP) directory to store authentication and authorization information about  
users of Cisco Unified CallManager applications that interface with  
Cisco Unified CallManager. Authentication establishes a user’s right to access  
the system. Authorization identifies the telephony resources that a user is  
permitted to use, such as a specific telephone extension.  
To install and set up these features, refer to Installing and Configuring the Cisco  
Unified Customer Directory Configuration Plugin. That manual guides you  
through the configuration process for integrating Cisco Unified CallManager  
with Microsoft Active Directory and Netscape Directory Server.  
After the LDAP directory configuration completes, the Corporate Directory  
service is enabled on your Cisco Unified IP Phone and allows users access to the  
corporate directory.  
Configuring Personal Directory  
Personal Directory consists of the following features:  
Personal Address Book (PAB)  
Personal Fast Dials (Fast Dials)  
Address Book Synchronization Tool (TABSynch)  
Users can access Personal Directory features by these methods:  
From a web browser—Users can access the PAB and Fast Dials features from  
the Cisco Unified CallManager User Options web pages  
From the Cisco Unified IP Phone—Users can choose Directories > Personal  
Directory to access the PAB and Fast Dials features from their phones  
From a Microsoft Windows application—Users can use the TABSynch tool  
to synchronize their PABs with Microsoft Outlook.  
To configure Personal Directory from a web browsers, users must access their  
User Options web pages. You must provide users with a URL and login  
information.

The Cisco Unified IP Phone ships with two default ring types that are  
implemented in hardware: Chirp1 and Chirp2. Cisco Unified CallManager also  
software as pulse code modulation (PCM) files. The PCM files, along with an  
Cisco Unified CallManager server.  
The following sections describe how you can customize the phone rings that are  
available at your site by creating PCM files and editing the Ringlist.xml file:

Chapter 6 Customizing the Cisco Unified IP Phone  
Creating Custom Phone Rings  
Ringlist.xml File Format Requirements  
The Ringlist.xml file defines an XML object that contains a list of phone ring  
types. This file can include up to 50 ring types. Each ring type contains a pointer  
to the PCM file that is used for that ring type and the text that will appear on the  
Ring Type menu on a Cisco Unified IP Phone for that ring. The Cisco TFTP  
server for each Cisco Unified CallManager contains this file.  
The CiscoIPPhoneRinglist XML object uses the following simple tag set to  
describe the information:  
<CiscoIPPhoneRingList>  
<Ring>  
<DisplayName/>  
<FileName/>  
</Ring>  
</CiscoIPPhoneRingList>  
The following characteristics apply to the definition names. You must include the  
required DisplayName and FileName for each phone ring type.  
DisplayName defines the name of the custom ring for the associated PCM file  
that will display on the Ring Type menu of the Cisco Unified IP Phone.  
FileName specifies the name of the PCM file for the custom ring to associate  
with DisplayName.  
Note  
The DisplayName and FileName fields must not exceed 25 characters.  
This example shows a Ringlist.xml file that defines two phone ring types:  
<CiscoIPPhoneRingList>  
<Ring>  
<DisplayName>Analog Synth 1</DisplayName>  
<FileName>Analog1.raw</FileName>  
</Ring>  
<Ring>  
<DisplayName>Analog Synth 2</DisplayName>

PCM File Requirements for Custom Ring Types  
The PCM files for the rings must meet the following requirements for proper  
playback on Cisco Unified IP Phones:  
Raw PCM (no header)  
8000 samples per second  
8 bits per sample  
uLaw compression  
Maximum ring size—16080 samples  
Minimum ring size—240 samples  
Number of samples in the ring is evenly divisible by 240.  
Ring starts and ends at the zero crossing.  
To create PCM files for custom phone rings, you can use any standard audio  
editing packages that support these file format requirements.  
Configuring a Custom Phone Ring  
follow these steps:  
Procedure  
Step 1  
Step 2  
Create a PCM file for each custom ring (one ring per file). Ensure the PCM files  
comply with the format guidelines that are listed in the “PCM File Requirements  
for Custom Ring Types” section on page 6-4.  
Place the new PCM files that you created in the TFTP server for each  
Cisco Unified CallManager in your cluster. For more information, see the  
“Software Upgrades” chapter in Cisco IP Telephony Platform Administration  
Guide.  
Step 3

PNG File Requirements for Custom Background Images, page 6-6.  
Configuring a Custom Background Image, page 6-7  
List.xml File Format Requirements  
The List.xml file defines an XML object that contains a list of background  
images. The List.xml file is stored in the following folder on the TFTP server:  
Tip  
If you are manually creating the directory structure and the List.xml file, you must  
ensure that the directories and files can be accessed by the user\CCMService,  
which is used by the TFTP service.

OL-11524-01  
6-5  
           
Chapter 6 Customizing the Cisco Unified IP Phone  
Creating Custom Background Images  
The List.xml file can include up to 50 background images. The images are in the  
order that they appear in the Background Images menu on the phone. For each  
image, the List.xml file contains one element type, called ImageItem. The  
ImageItem element includes these two attributes:  
Image—Uniform resource identifier (URI) that specifies where the phone  
obtains the thumbnail image that will appear on the Background Images menu  
on a Phone.  
URL—URI that specifies where the phone obtains the full size image.  
The following example shows a List.xml file that defines two images. The  
required Image and URL attributes must be included for each image. The TFTP  
URI that is shown in the example is the only supported method for linking to full  
size and thumbnail images. HTTP URL support is not provided.  
List.xml Example  
<CiscoIPPhoneImageList>  
<ImageItem Image=”TFTP:Desktops/320x212x12/TN-Fountain.png”  
URL=”TFTP:Desktops/320x212x12/Fountain.png”/>  
<ImageItem Image=”TFTP:Desktops/320x212x12/TN-FullMoon.png”  
URL=”TFTP:Desktops/320x212x12/FullMoon.png”/>  
</CiscoIPPhoneImageList>  
The Cisco Unified IP Phone firmware includes a default background image. This  
image is not defined in the List.xml file. The default image is always the first  
image that appears in the Background Images menu on the phone.  
PNG File Requirements for Custom Background Images  
Each background image requires two PNG files:  
Full size image—Version that appears on the on the phone.  
Thumbnail image—Version that appears on the Background Images screen  
from which users can select an image. Must be 25% of the size of the full size  
image.

OL-11524-01  
6-6  
   
Chapter 6 Customizing the Cisco Unified IP Phone  
Creating Custom Background Images  
Tip  
Many graphics programs provide a feature that will resize a graphic. An easy way  
to create a thumbnail image is to first create and save the full size image, then use  
the sizing feature in the graphics program to create a version of that image that is  
25% of the original size. Save the thumbnail version using a different name.  
The PNG files for background images must meet the following requirements for  
proper display on the Cisco Unified IP Phone:  
Full size image—320 pixels (width) X 212 pixels (height).  
Thumbnail image—80 pixels (width) X 53 pixels (height).  
Color palette—Includes up to 12-bit color (4096 colors). You can use more  
than 12-bit color, but the phone will reduce the color palette to12-bit before  
displaying the image. For best results, reduce the color palette of an image to  
12-bit when you create a PNG file.  
Tip  
If you are using a graphics program that supports a posterize feature for  
specifying the number of tonal levels per color channel, set the number of  
tonal levels per channel to 16 (16 red X 16 green X 16 blue = 4096 colors).  
Configuring a Custom Background Image  
these steps:  
Procedure  
Step 1  
Step 2  
Create two PNG files for each image (a full size version and a thumbnail version).  
Ensure the PNG files comply with the format guidelines that are listed in the  
“PNG File Requirements for Custom Background Images” section on page 6-6.  
Place the new PNG files that you created in the folder on the TFTP server for each  
Cisco Unified CallManager in the cluster. For more information, see the  
“Software Upgrades” chapter in the Cisco IP Telephony Platform Administration  
Guide.

Chapter 6 Customizing the Cisco Unified IP Phone  
Configuring Wideband Headset Codec  
Note  
Cisco recommends that you also store backup copies of custom image  
files in another location. You can use these backup copies if the  
customized files are overwritten when you upgrade  
Cisco Unified CallManager.  
Step 3  
Step 4  
Use a text editor to edit the List.xml file. See the “List.xml File Format  
Requirements” section on page 6-5 for the location of this file, formatting  
requirements, and a sample file.  
Save your modifications and close the List.xml file.  
Note  
When you upgrade Cisco Unified CallManager, a default List.xml file  
will replace your customized List.xml file. After your customize the  
List.xml file, make a copy of the file and store it in another location. After  
upgrading Cisco Unified CallManager, replace the default List.xml file  
with your stored copy.  
Step 5  
To cache the new List.xml file, stop and start the TFTP service by using  
Cisco Unified CallManager Serviceability or disable and re-enable the Enable  
Caching of Constant and Bin Files at Startup TFTP service parameter (located in  
the Advanced Service Parameters).  
Configuring Wideband Headset Codec  
Users can configure a setting called Wideband Headset in the Audio Preferences  
menu on the phone (choose > User Preferences > Audio Preferences>  
Wideband Headset). This setting is Disabled by default, and should be enabled  
only if the user’s headset supports wideband.  
If Cisco Unified CallManager has been configured to use G.722 (G.722 is enabled  
by default for Cisco Unified IP Phone Models 7941G, 7941G-GE, 7961G,  
7961G-GE, 7970G, and 7971G-GE; other phone models may not support it), and  
the far endpoint also supports G.722, the call will be connected using the G.722  
codec in place of G.711. This occurs regardless of whether the user has enabled a  
wideband headset, but if the headset is enabled, the headset user may notice

Configuring the Idle Display  
greater audio sensitivity during the call. Greater sensitivity means improved audio  
clarity but also means that more background noise can be heard by the far  
endpoint—noise such as rustling papers or nearby conversations. Even without a  
wideband headset, some users may prefer the additional sensitivity of G.722;  
conversely, some users may be distracted by the additional sensitivity of G.722.  
Two parameters in Cisco Unified CallManager Administration affect whether  
wideband is supported for this Cisco Unified CallManager server and/or a specific  
phone:  
Advertise G.722 Codec—Choose Cisco Unified CallManager  
Administration > System > Enterprise Parameters. The default value of  
this enterprise parameter is True, which means that all Cisco Unified IP  
Phone Models 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and  
7971G-GE that are registered to this Cisco Unified CallManager will  
advertise G.722 to Cisco Unified CallManager. If each endpoint in the  
attempted call supports G.722 in its capabilites set, Cisco Unified CallManager  
will choose that codec for the call. For more information, see the Cisco  
Unified CallManager 5.1 Release Notes.  
Advertise G.722 Codec—Choose Cisco Unified CallManager  
Administration > Device > Phone. The default value of this product-specific  
parameter is to use the value specified in the enterprise parameter. If you want  
to override this on a per-phone basis, choose Enabled or Disabled in the  
Advertise G.722 Codec parameter on the Product Specific Configuration area  
of the Phone Configuration window.  
Configuring the Idle Display  
You can specify an idle display that appears on the phone’s LCD screen. The idle  
display is an XML service that the phone invokes when the phone has been idle  
(not in use) for a designated period and no feature menu is open.  
XML services that can be used as idle displays include company logos, product  
pictures, and stock quotes.  
Configuring the idle display consists of these general steps.  
1. Formatting an image for display on the phone.  
2. Configure Cisco Unified CallManager to display the image on the phone.

Chapter 9 Troubleshooting and Maintenance  
Resolving Startup Problems  
After installing a Cisco Unified IP Phone into your network and adding it to  
Cisco Unified CallManager, the phone should start up as described in the  
start up properly, see the following sections for troubleshooting information:  
Symptom: The Cisco Unified IP Phone Does Not Go Through its Normal  
Startup Process, page 9-2  
Symptom: The Cisco Unified IP Phone Does Not Register with Cisco  
Unified CallManager, page 9-3  
Symptom: Cisco Unified IP Phone Unable to Obtain IP Address, page 9-8  
Symptom: The Cisco Unified IP Phone Does Not Go Through its  
Normal Startup Process  
When you connect a Cisco Unified IP Phone into the network port, the phone  
should go through its normal startup process as described in the Verifying the  
Phone Startup Process” section on page 3-15, and the LCD screen should display  
information. If the phone does not go through the startup process, the cause may  
be faulty cables, bad connections, network outages, lack of power, and so on. Or,  
the phone may not be functional.  
To determine whether the phone is functional, follow these suggestions to  
systematically eliminate these other potential problems:  
1. Verify that the network port is functional:  
Exchange the Ethernet cables with cables that you know are functional.  
Disconnect a functioning Cisco Unified IP Phone from another port and  
connect it to this network port to verify the port is active.  
Connect the Cisco Unified IP Phone that will not start up to a different  
network port that is known to be good.  
Connect the Cisco Unified IP Phone that will not start up directly to the  
port on the switch, eliminating the patch panel connection in the office.

Resolving Startup Problems  
2. Verify that the phone is receiving power:  
If you are using external power, verify that the electrical outlet is  
functional.  
If you are using in-line power, use the external power supply instead.  
If you are using the external power supply, switch with a unit that you  
know to be functional.  
If you are using a Cisco Unified IP Phone 7971G-GE, make sure that the  
phone is connected to a switch that supports IEEE 802.3af Class 3 (15.4  
W in-line power at the switch port). For more information, see the  
“Providing Power to the Phone” section on page 2-4.  
3. If the phone still does not start up properly, power up the phone with the  
handset off-hook. When the phone is powered up in this way, it attempts to  
launch a backup software image.  
4. If the phone still does not start up properly, perform a factory reset of the  
phone. For instructions, see the “Performing a Factory Reset” section on  
page 9-19.  
If after attempting these solutions, the LCD screen on the Cisco Unified IP Phone  
does not display any characters after at least five minutes, contact a Cisco  
technical support representative for additional assistance.  
Symptom: The Cisco Unified IP Phone Does Not Register with  
Cisco Unified CallManager  
If the phone proceeds past the first stage of the startup process (LED buttons  
flashing on and off) but continues to cycle through the messages displaying on the  
start up unless it is connected to the Ethernet network and it has registered with a  
Cisco Unified CallManager server.  
These sections can assist you in determining the reason the phone is unable to start  
up properly:

Registering the Phone with Cisco Unified CallManager, page 9-8  
In addition, problems with security may prevent the phone from starting up  
page 9-12for more information.  
Identifying Error Messages  
As the phone cycles through the startup process, you can access status messages  
that might provide you with information about the cause of a problem. See the  
“Status Messages Screen” section on page 7-4 for instructions about accessing  
status messages and for a list of potential errors, their explanations, and their  
solutions.  
Checking Network Connectivity  
If the network is down between the phone and the TFTP server or  
Cisco Unified CallManager, the phone cannot start up properly. Ensure that the  
network is currently running.  
You can determine the IP address of the TFTP server used by the phone by  
pressing the Settings button on the phone, choosing Network Configuration,  
and scrolling to the TFTP Server 1 option.  
If you have assigned a static IP address to the phone, you must manually enter a  
setting for the TFTP Server 1 option. See the “Network Configuration Menu”  
section on page 4-7.

Chapter 9 Troubleshooting and Maintenance  
Resolving Startup Problems  
If you are using DHCP, the phone obtains the address for the TFTP server from  
the DHCP server. Check the IP address configured in Option 150.  
You can also enable the phone to use an alternate TFTP server. Such a setting is  
particularly useful if the phone was recently moved from one location to another.  
See the “Network Configuration Menu” section on page 4-7 for instructions.  
Verifying IP Addressing and Routing  
You should verify the IP addressing and routing settings on the phone. If you are  
using DHCP, the DHCP server should provide these values. If you have assigned  
a static IP address to the phone, you must enter these values manually.  
On the Cisco Unified IP Phone, press the Settings button, choose Network  
Configuration, and look at the following options:  
DHCP Server—If you have assigned a static IP address to the phone, you do  
using a DHCP server, this option must have a value. If it does not, check your  
IP routing and VLAN configuration. Refer to Troubleshooting Switch Port  
Problems, available at this URL:  
IP Address, Subnet Mask, Default Router—If you have assigned a static IP  
address to the phone, you must manually enter settings for these options. See  
the “Network Configuration Menu” section on page 4-7 for instructions.  
If you are using DHCP, check the IP addresses distributed by your DHCP server.  
Refer to Understanding and Troubleshooting DHCP in Catalyst Switch or  
Enterprise Networks, available at this URL:

Chapter 9 Troubleshooting and Maintenance  
Resolving Startup Problems  
Verifying DNS Settings  
If you are using DNS to refer to the TFTP server or to  
Cisco Unified CallManager, you must ensure that you have specified a DNS  
server. Verify this setting by pressing the Settings button on the phone, choosing  
Network Configuration, and scrolling to the DNS Server 1 option. You should  
also verify that there is a CNAME entry in the DNS server for the TFTP server  
and for the Cisco Unified CallManager system.  
You must also ensure that DNS is configured to do reverse look-ups.  
Verifying Cisco Unified CallManager Settings  
On the Cisco Unified IP Phone, press the Settings button, choose Network  
Configuration, and look at the CallManager 15 options. The Cisco Unified IP  
Phone attempts to open a TCP connection to all the Cisco Unified CallManager  
servers that are part of the assigned Cisco Unified CallManager group. If none of  
these options contain IP addresses or show Active or Standby, the phone is not  
properly registered with Cisco Unified CallManager. See the “Registering the  
Phone with Cisco Unified CallManager” section on page 9-8 for tips on resolving  
this problem.  
Cisco Unified CallManager and TFTP Services Are Not Running  
If the Cisco Unified CallManager or TFTP services are not running, phones may  
not be able to start up properly. However, in such a situation, it is likely that you  
are experiencing a system-wide failure and that other phones and devices are  
If the Cisco Unified CallManager service is not running, all devices on the  
network that rely on it to make phone calls will be affected. If the TFTP service  
is not running, many devices will not be able to start up successfully.  
To start a service, follow these steps:  
Procedure  
Step 1  
Step 2  
From Cisco Unified CallManager Administration, choose Application >  
Cisco CallManager Serviceability.  
Choose Tools > Control Center.

Step 4  
From the Servers column, choose the primary Cisco Unified CallManager server.  
The page displays the service names for the server that you chose, the status of  
the services, and a service control panel to stop or start a service.  
If a service has stopped, click the Start button.  
The Service Status symbol changes from a square to an arrow.  
Creating a New Configuration File  
If you continue to have problems with a particular phone that other suggestions in  
this chapter do not resolve, the configuration file may be corrupted.  
To create a new configuration file, follow these steps:  
Procedure  
Step 1  
Step 2  
Step 3  
From Cisco Unified CallManager, choose Device > Phone > Find to locate the  
phone experiencing problems.  
Choose Delete to remove the phone from the Cisco Unified CallManager  
database.  
Add the phone back to the Cisco Unified CallManager database. See the “Adding  
Phones to the Cisco Unified CallManager Database” section on page 2-13 for  
details.  
Step 4  
Note  
Power cycle the phone.  
When you remove a phone from the Cisco Unified CallManager database, its  
configuration file is deleted from the Cisco Unified CallManager TFTP  
server. The phone’s directory number or numbers remain in the Cisco Unified  
CallManager database. They are called “unassigned DNs” and can be used for  
other devices. If unassigned DNs are not used by other devices, delete them  
from the Cisco Unified CallManager database. You can use the Route Plan  
Report to view and delete unassigned reference numbers. Refer to  
Cisco Unified CallManager Administration Guide for more information.

Chapter 9 Troubleshooting and Maintenance  
Resolving Startup Problems  
Changing the buttons on a phone button template, or assigning a different  
phone button template to a phone, may result in directory numbers that are no  
longer accessible from the phone. The directory numbers are still assigned to  
the phone in the Cisco Unified CallManager database, but there is no button  
on the phone with which calls can be answered. These directory numbers  
should be removed from the phone and deleted if necessary.  
Registering the Phone with Cisco Unified CallManager  
A Cisco Unified IP Phone can register with a Cisco Unified CallManager server  
Review the information and procedures in the “Adding Phones to the Cisco  
Unified CallManager Database” section on page 2-13 to ensure that the phone has  
been added to the Cisco Unified CallManager database.  
To verify that the phone is in the Cisco Unified CallManager database, choose  
Device > Find from Cisco Unified CallManager Administration to search for the  
phone based on its MAC Address. For information about determining a MAC  
address, see the “Determining the MAC Address of a Cisco Unified IP Phone”  
section on page 2-20.  
If the phone is already in the Cisco Unified CallManager database, its  
configuration file may be damaged. See the “Creating a New Configuration File”  
section on page 9-7 for assistance.  
Symptom: Cisco Unified IP Phone Unable to Obtain IP Address  
If a phone is unable to obtain an IP address when it starts up, the phone may be  
not be on the same network or VLAN as the DHCP server, or the switch port to  
which the phone is connected may be disabled.  
Make sure that the network or VLAN to which the phone is connected has access  
to the DHCP server, and make sure that the switch port is enabled.

Cisco Unified IP Phone Resets Unexpectedly  
Cisco Unified IP Phone Resets Unexpectedly  
If users report that their phones are resetting during calls or while idle on their  
desk, you should investigate the cause. If the network connection and  
Typically, a phone resets if it has problems connecting to the Ethernet network or  
to Cisco Unified CallManager. These sections can help you identify the cause of  
a phone resetting in your network:  
Checking Static IP Address Settings, page 9-10  
Verifying Voice VLAN Configuration, page 9-10  
Verifying that the Phones Have Not Been Intentionally Reset, page 9-11  
Eliminating DNS or Other Connectivity Errors, page 9-11  
Checking Power Connection, page 9-12  
Verifying Physical Connection  
Verify that the Ethernet connection to which the Cisco Unified IP Phone is  
connected is up. For example, check if the particular port or switch to which the  
phone is connected is down and that the switch is not rebooting. Also make sure  
that there are no cable breaks.  
Identifying Intermittent Network Outages  
Intermittent network outages affect data and voice traffic differently. Your  
network might have been experiencing intermittent outages without detection. If  
so, data traffic can resend lost packets and verify that packets are received and  
transmitted. However, voice traffic cannot recapture lost packets. Rather than  
retransmitting a lost network connection, the phone resets and attempts to  
reconnect its network connection.

If you are experiencing problems with the voice network, you should investigate  
whether an existing problem is simply being exposed.  
Verifying DHCP Settings  
Follow this process to help determine if the phone has been properly configured  
to use DHCP:  
1. Verify that you have properly configured the phone to use DHCP. See the  
“Network Configuration Menu” section on page 4-7 for more information.  
2. Verify that the DHCP server has been set up properly.  
3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.  
Cisco Unified IP Phones send messages with request type 151 to renew their  
DHCP address leases. If the DHCP server expects messages with request type  
IP address from the DHCP server.  
Checking Static IP Address Settings  
If the phone has been assigned a static IP address, verify that you have entered the  
correct settings. See the “Network Configuration Menu” section on page 4-7 for  
more information.  
If the Cisco Unified IP Phone appears to reset during heavy network usage (for  
example, following extensive web surfing on a computer connected to same  
switch as phone), it is likely that you do not have a voice VLAN configured.  
Isolating the phones on a separate auxiliary VLAN increases the quality of the  
voice traffic. See the “Understanding How the Cisco Unified IP Phone Interacts  
with the VLAN” section on page 2-3 for details.

Cisco Unified IP Phone Resets Unexpectedly  
Verifying that the Phones Have Not Been Intentionally Reset  
If you are not the only administrator with access to Cisco Unified CallManager,  
you should verify that no one else has intentionally reset the phones.  
You can check whether a Cisco Unified IP Phone received a command from  
Cisco Unified CallManager to reset by pressing the Settings button on the phone  
and choosing Status > Network Statistics. If the phone was recently reset one of  
these messages appears:  
Reset-Reset—Phone closed due to receiving a Reset/Reset from  
Cisco Unified CallManager administration.  
Reset-Restart—Phone closed due to receiving a Reset/Restart from  
Cisco Unified CallManager administration.  
If the phone continues to reset, follow these steps to eliminate DNS or other  
connectivity errors:  
Step 1  
Step 2  
Use the Erase softkey to reset phone settings to their default values. See the  
“Resetting or Restoring the Cisco Unified IP Phone” section on page 9-17 for  
details.  
Modify DHCP and IP settings.  
a. Disable DHCP. See the “Network Configuration Menu” section on page 4-7  
for instructions.  
b. Assign static IP values to the phone. See the “Network Configuration Menu”  
section on page 4-7 for instructions. Use the same default router setting used  
for other functioning Cisco Unified IP Phones.  
c. Assign TFTP server. See the “Network Configuration Menu” section on  
page 4-7 for instructions. Use the same TFTP server used for other  
functioning Cisco Unified IP Phones.  
Step 3  
Step 4  
On the Cisco Unified CallManager server, verify that the local host files have the  
correct Cisco Unified CallManager server name mapped to the correct IP address.  
From Cisco Unified CallManager, choose System > Server and verify that the  
server is referred to by its IP address and not by its DNS name.

have assigned the correct MAC address to this Cisco Unified IP Phone. For  
information about determining a MAC address, see the “Determining the MAC  
Address of a Cisco Unified IP Phone” section on page 2-20.  
Power cycle the phone.  
Checking Power Connection  
In most cases, a phone will restart if it powers up using external power but loses  
that connection and switches to PoE. Similarly, a phone may restart if it powers  
up using PoE and then gets connected to an external power supply.

Caution  
The computer’s network card cannot receive power  
through the network connection; if power comes  
through the connection, the network card can be  
destroyed. To protect a network card, wait 10  
seconds or longer after unplugging the cable from  
the phone before plugging it into a computer. This  
delay gives the switch enough time to recognize that  
there is no longer a phone on the line and to stop  
providing power to the cable.

By default, the network configuration options are locked to  
prevent users from making changes that could impact their  
network connectivity. You must unlock the network  
configuration options before you can configure them. See the  
“Unlocking and Locking Options” section on page 4-4 for  
details.  
LCD display issues.  
If the display appears to have rolling lines or a wavy pattern, it  
might be interacting with certain types of older fluorescent  
lights in the building. Moving the phone away from the lights,  
or replacing the lights, should resolve the problem.

Chapter 9 Troubleshooting and Maintenance  
Using the Quality Report Tool  
After you press these keys, the line buttons on the phone flash orange and then  
green, and the phone goes through the factory reset process. This process can take  
several minutes.  
Do not power down the phone until it completes the factory reset process and the  
main screen appears.  
Using the Quality Report Tool  
The Quality Report Tool (QRT) is a voice quality and general problem-reporting  
tool for the Cisco Unified IP Phone. The QRT feature is installed as part of the  
Cisco Unified CallManager installation.  
You can configure users’ Cisco Unified IP Phones with QRT. When you do so,  
users can report problems with phone calls by pressing the QRT softkey. This  
softkey is available only when the Cisco Unified IP Phone is in the Connected,  
Connected Conference, Connected Transfer, and/or OnHook states.  
When a user presses the QRT softkey, a list of problem categories appears. The  
user selects the appropriate problem category and this feedback is logged in an  
XML file. Actual information logged depends on the user selection and whether  
the destination device is a Cisco Unified IP Phone.  
For more information about using QRT, refer to Cisco Unified CallManager  
Features and Services Guide.  
Monitoring the Voice Quality of Calls  
To measure the voice quality of calls that are sent and received within the  
network, Cisco Unified IP Phones use these statistical metrics that are based on  
concealment events. The DSP plays concealment frames to mask frame loss in the  
voice packet stream.  
Concealment Ratio metrics—Show the ratio of concealment frames over total  
speech frames. An interval conceal ratio is calculated every 3 seconds.  
Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones  
OL-11524-01  
9-20  
         
Chapter 9 Troubleshooting and Maintenance  
Monitoring the Voice Quality of Calls  
Concealed Second metrics—Show the number of seconds in which the DSP  
plays concealment frames due to lost frames. A severely “concealed second”  
is a second in which the DSP plays more than five percent concealment  
frames.  
MOS-LQK metrics—Use a numeric score to estimate the relative voice  
listening quality. The Cisco Unified IP Phone calculates the mean opinion  
score (MOS) for listening quality (LQK) based audible concealment events  
due to frame loss in the preceding 8 seconds, and includes perceptual  
weighting factors such as codec type and frame size.  
MOS LQK scores are produced by a Cisco proprietary algorithm, Cisco Voice  
Transmission Quality (CVTQ) index. Depending on the MOS LQK version  
number, these scores might be compliant with the International  
Telecommunications Union (ITU) standard P.564. This standard defines  
evaluation methods and performance accuracy targets that predict listening  
quality scores based on observation of actual network impairment.  
Note  
Concealment ratio and concealment seconds are primary measurements based on  
frame loss while MOS LQK scores project a “human-weighted” version of the  
same information on a scale from 5 (excellent) to 1 (bad) for measuring listening  
quality.  
Listening quality scores (MOS LQK) relate to the clarity or sound of the received  
voice signal. Conversational quality scores (MOS CQ such as G.107) include  
impairment factors, such as delay, that degrade the natural flow of conversation.  
You can access voice quality metrics from the Cisco Unified IP Phone by using  
the Call Statistics screen (see the “Call Statistics Screen” section on page 7-16 )  
or remotely by using Streaming Statistics (see the “Monitoring the Cisco  
Unified IP Phone Remotely” chapter.  
Using Voice Quality Metrics  
To use the metrics for monitoring voice quality, note the typical scores under  
normal conditions of zero packet loss , and use the metrics as a baseline for  
comparison.  
Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones  
OL-11524-01

Chapter 9 Troubleshooting and Maintenance  
Monitoring the Voice Quality of Calls  
It is important to distinguish significant changes from random changes in metrics.  
Significant changes are scores that change about 0.2 MOS or greater and persist  
in calls that last longer than 30 seconds. Conceal Ratio changes should indicate  
greater than 3 percent frame loss.  
MOS LQK scores can vary based on the codec that the Cisco Unified IP Phone  
uses. The following codecs provide these maximum MOS LQK scores under  
normal conditions with zero frame loss:  
G.711 codec gives 4.5 score  
G.719A/ AB gives 3.7 score  
Note  
CVTQ does not support wideband (7 kHz) speech codecs, as ITU has not  
defined the extension of the technique to wideband. Therefore, MOS scores  
that correspond to G.711 performance are reported for G.722 calls to allow  
basic quality monitoring, rather than not reporting an MOS score.  
Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ  
allows basic quality classifications to be indicated as good/normal or  
bad/abnormal. Calls with high scores (approximately 4.5) indicate high  
quality/low packet loss, and lower scores (approximately 3.5) indicate low  
quality/high packet loss.  
Unlike MOS, the Conceal Ratio and Concealed Seconds metrics remain valid  
and useful for both wideband and narrowband calls.  
A Conceal Ratio of zero indicates that the IP network is delivering frames and  
packets on time with no loss.  
Troubleshooting Tips  
When you observe significant and persistent changes to metrics, use Table 9-4 for  
general troubleshooting information.

Cleaning the Cisco Unified IP Phone  
To clean your Cisco Unified IP phone, use a soft, dry cloth to wipe the phone and  
the touchscreen. Do not apply liquids or powders directly on the phone. As with  
all non-weather-proof electronics, liquids and powders can damage the  
components and cause failures.  
Disable the touchscreen before cleaning it so that you will not inadvertently  
choose a feature from the pressure of the cleaning cloth. To disable the  
touchscreen so that it will not respond to touch, press the Display button for more  
than one second. The phone displays Touchscreen Disabled and the Display  
button flashes green.  
After one minute, the touchscreen automatically re-enables itself. To re-enable  
the touchscreen before that, press the flashing Display button for more than one  
second. The phone displays Touchscreen Enabled.

Supporting International Users  
Translated and localized versions of the Cisco Unified IP Phones are available in  
several languages. If you are supporting Cisco Unified IP Phones in a non-English  
environment, refer to the following sections to ensure that the phones are set up  
properly for your users:  
Adding Language Overlays to Phone Buttons, page C-1  
Installing the Cisco Unified CallManager Locale Installer, page C-2  
Adding Language Overlays to Phone Buttons  
To support the needs of international users, the button labels on the  
Cisco Unified IP Phones exhibit icons rather than text to indicate the purposes of  
the buttons. You can purchase language-specific text overlays to add to a phone.  
To order these language-specific overlays, go to this website:  
Note  
Phone overlays are available only for languages in which the Cisco Unified IP  
Phone software has been localized. All languages may not be immediately  
available, so continue to check the website for updates.

Appendix C Supporting International Users  
Installing the Cisco Unified CallManager Locale Installer  
Installing the Cisco Unified CallManager Locale  
Installer  
If you are using Cisco Unified IP Phones in a locale other than English, you must  
install the locale-specific version of the Cisco Unified CallManager Locale  
Installer on every Cisco Unified CallManager server in the cluster. Installing the  
locale installer ensures that you have the latest translated text, user and network  
locales, and country-specific phone tones available for the  
Cisco Unified IP Phones. You can find locale-specific versions of the Cisco  
Unified CallManager Locale Installer at  
tml.  
For more information, refer to the “Locale Installation” section in the Cisco IP  
Telephony Platform Administration Guide.  
Note  
All languages may not be immediately available, so continue to check the website  
for updates.
