Chapter 1 An Overview of the Cisco Unified IP Phone

What Features are Supported on the Cisco Unified IP Phones 7960G and 7940G?

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 and for tips on configuring them, see the “Telephony

Features Available for the Cisco Unified IP 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 Communications Manager and the rest of the IP network. By using DHCP, you have fewer

settings to configure on a phone, but if your network requires it, you can manually configure an IP

address, TFTP server, and subnet mask. For instructions on configuring the network settings on the

Cisco Unified IP Phones, see Chapter 4, “Configuring Network 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-worker 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 other web-based information. For

information about configuring such services, see the “Configuring Corporate Directories” section on

page 5-9 and the “Setting Up Services” section on page 5-11.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status

information from it directly. This information can assist you with troubleshooting any problems users

might encounter when using their IP phones. See Chapter 6, “Viewing Model Information, Status,

Statistics, and Security Information on the Cisco Unified IP Phone,” for more information.

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:

http://www.cisco.com/en/US/products/hw/phones/ps379/tsd_products_support_series_home.html

From this site, you can view access various user guides.

In addition to providing documentation, it is important to inform users of available Cisco Unified IP

Phone features—including those specific to your company or network—and of 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 a Website.”

Understanding Security Features for Cisco Unified IP Phones

Implementing security in the Cisco Unified Communications Manager system prevents identity theft of

the phone and Cisco Unified Communications Manager server, prevents data tampering, and prevents

call signaling and media stream tampering.

To alleviate these threats, the Cisco Unified 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.

Table 1-2 shows where you can find additional information about security in this and other documents.

Overview of Supported Security Features

Table 1-3 provides an overview of the security features that the Cisco Unified IP Phones support. For

more information about these features and about Cisco Unified Communications Manager and

Cisco Unified IP Phone security, refer to Cisco Unified Communications Manager Security Guide.

For information about current security settings on a phone, choose Settings > Security Configuration.

For more information, see the “Security Configuration Menu” section on page 6-12.

Note

Most security features are available only if a certificate trust list (CTL) is installed on the phone. For

more information about the CTL, refer to “Configuring the Cisco CTL Client” chapter in Cisco Unified

Communications Manager Security Guide.

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 (MIC), but for additional security, you

can specify in Cisco Unified Communications Manager Administration that a certificate be

installed by using the CAPF. Alternatively, you can install an LSC from the Security

Configuration menu on the phone. See the “Configuring Security on the Cisco Unified IP

Phone” section on page 3-10 for more information.

Device authentication

Occurs between the Cisco Unified Communications Manager 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 Communications Manager should

occur, and, if necessary, creates a secure signaling path between the entities using TLS

protocol. Cisco Unified Communications Manager will not register phones unless they can

be authenticated by the Cisco Unified Communications Manager.

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 Communications Manager to authenticate the

phone.

Secure SRST reference

After you configure a SRST reference for security and then reset the dependent devices in

Cisco Unified Communications Manager Administration, the TFTP server adds the SRST

certificate to the phone cnf.xml file and sends the file to the phone. A secure phone then

uses a TLS connection to interact with the SRST-enabled router.

Feature

Description

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.

Signaling Encryption

Ensures that all SCCP signaling messages that are sent between the device and the Cisco

Unified Communications Manager 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.

Optional disabling of the web

You can prevent access to a phone’s web page, which displays a variety of operational

server functionality for a phone statistics for the phone.

Phone hardening Additional security options, which you control from Cisco Unified Communications

Manager Administration:

•

Disabling PC port

Disabling Gratuitous ARP (GARP)

Disabling PC Voice VLAN access

Disabling access to the Setting menus, or providing restricted access that allows access

to the User Preferences menu and saving volume changes only

•

Disabling access to web pages for a phone.

Note

You can view current settings for the PC Port Disabled, GARP Enabled, and Voice

VLAN enabled options by looking at the phone’s Network Configuration menu.

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 screen on the phone.

In an authenticated call, all devices participating in the establishment of the call are authenticated by the

Cisco Unified Communications Manager. When a call in progress is authenticated, the call progress icon

to the right of the call duration timer in the phone LCD screen changes to the following icon:

In an encrypted call, all devices participating in the establishment of the call are authenticated by the

Cisco Unified Communications Manager. 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, PSTN, the call may be nonsecure even though

it is encrypted within the IP network and has a lock icon associated with it.

Security Restrictions, page 1-11

Security Restrictions

The following restrictions apply to encrypted calls:

•

When establishing an encrypted call on a phone that is configured for encryption and associated with

a wideband codec region, Cisco Unified Communications Manager ignores the wideband codec and

chooses another supported codec from the codec list that the phone presents. If the other devices in

the call are not configured for encryption, Cisco Unified Communications Manager may establish

the authenticated/nonsecure call by using the wideband codec.

•

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.

Chapter 1 An Overview of the Cisco Unified IP Phone

Overview of Configuring and Installing Cisco Unified IP Phones

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 Communications

Manager 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.

CAPF Interaction when the Phone Resets

The following examples describe how CAPF interacts with the Cisco Unified IP Phone when the phone

is reset by a user or by Cisco Unified Communications Manager. In these examples, if an LSC does not

already exist in the phone and if By Existing Certificate is selected for the CAPF Authentication Mode,

the CAPF certificate operation will fail.

Example 1

In this example the phone is reset after you configure the Device Security Mode to Nonsecure and the

CAPF Authentication Mode to By Null String or By Existing Certificate (Precedence...). After the phone

resets, it immediately registers with the primary Cisco Unified Communications Manager and receives

the configuration file. The phone then automatically initiates a session with CAPF to download the LSC.

After the LSC exists in the phone, configure the Device Support Mode to Authenticated or Encrypted.

Example 2

In this example, the phone is reset after you configure the Device Security Mode to Authenticated or

Encrypted and the CAPF Authentication Mode to By Null String or By Existing Certificate

(Precedence...). The phone does not register with the primary Cisco Unified Communications Manager

until the CAPF session ends and the phone has installed the LSC. After the session ends, the phone

registers and immediately runs in authenticated or encrypted mode.

You cannot configure By Authentication String in this example because the phone will not automatically

contact the CAPF server and the registration will fail if the phone does not have a valid LSC.

Overview of Configuring and Installing Cisco Unified IP Phones

When deploying a new IP telephony system, system administrators and network administrators must

complete several initial configuration tasks to prepare the network for IP telephony service. For

Preparing to Install the Cisco Unified IP Phone on

Your Network

Cisco Unified IP Phones enable you to communicate using voice over a data network. To provide this

capability, the IP Phones depend upon and interact with several other key Cisco Unified IP Telephony

components, including Cisco Unified Communications Manager.

This chapter focuses on the interactions between the Cisco Unified IP Phone 7960G and 7940G and

Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers, and switches. It also

describes options for powering phones.

Understanding Interactions with Other Cisco

Unified IP Communications Products

To function in the IP telephony network, the Cisco Unified IP Phone must be connected to a networking

device, such as a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a

Cisco Unified Communications Manager system before sending and receiving calls.

Understanding How the Cisco Unified IP Phone Interacts with Cisco

Unified Communications Manager

Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco

Unified Communications Manager software sets up and tears down calls between phones, integrating

traditional PBX functionality with the corporate IP network. Cisco Unified Communications Manager

manages the components of the IP telephony system—the phones, the access gateways, and the resources

necessary for such features as call conferencing and route planning. Cisco Unified Communications

Manager also provides:

•

Firmware for phones

Authentication and encryption (if configured for the telephony system)

Configuration file and CTL file, via TFTP service

Phone registration

Call preservation, so that a media session continues if signaling is lost between the primary Cisco

Unified Communications Manager and a phone)

For information about configuring Cisco Unified Communications Manager to work with the IP devices

described in this chapter, refer to Cisco Unified Communications Manager Administration Guide, Cisco

Unified Communications Manager System Guide, and to Cisco Unified Communications Manager

Security Guide.

For an overview of security functionality for the Cisco Unified IP Phone, see the “Understanding

Security Features for Cisco Unified IP Phones” section on page 1-7.

Note

If the Cisco Unified IP Phone model that you want to configure does not appear in the Phone Type

drop-down list in Cisco Unified Communications Manager Administration, go to the following URL and

install the latest support patch for your version of Cisco Unified Communications Manager:

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network

Providing Power to the Cisco Unified IP Phone

Understanding How the Cisco Unified IP Phone Interacts with the VLAN

The Cisco Unified IP Phone 7960G and 7940G have an internal Ethernet switch, enabling proper

forwarding of appropriate packets to the phone, to the access port (labeled 10/100 PC on the phone), and

to the network port (labeled 10/100 SW on 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 addresses

might not be available to assign the phone to the same subnet as other devices connected to the same

port.

•

Data traffic present on the VLAN supporting phones might 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 increases the quality of the voice traffic and allows

a large number of phones to be added to an existing network where there are not enough IP addresses

for each phone.

Providing Power to the Cisco Unified IP Phone

The Cisco Unified IP Phone 7960G and 7940G can be powered with external power or with Power over

Ethernet (PoE). External power is provided through a separate power supply. PoE is provided by a switch

through the Ethernet cable attached to a phone.

Note

When you install a phone that is powered with external power, connect the power supply to the phone

and to a power outlet before you connect the Ethernet cable to the phone. When you remove a phone that

is powered with external power, disconnect the Ethernet cable from the phone before you disconnect the

power supply.

assign static IP addresses to each phone locally.

Access a TFTP server.

•

Adding Phones to the Cisco

In addition to assigning an IP address, the DHCP server

directs the Cisco Unified IP Phone to a TFTP Server. If the

phone has a statically-defined IP address, you must

configure the TFTP server locally on the phone; the phone

then contacts the TFTP server directly.

Note

You can also assign an alternative TFTP server to

use instead of the one assigned by DHCP.

Request the CTL file.

For more information, refer to the Cisco

Unified Communications Manager Security Guide

The TFTP server stores the certificate trust list (CTL) file.

This file contains a list of Cisco Unified Communications

Managers and TFTP servers that the phone is authorized to

connect to. It also contains the certificates necessary for

establishing a secure connection between the phone and

Cisco Unified Communications Manager.

The configuration file defines how the

Cisco Unified IP Phone communicates with

Cisco Unified Communications Manager and provides a

phone with its load ID. After obtaining the file from the

TFTP server, the phone attempts to make a connection to

the highest priority Cisco Unified Communications

Manager on the list. If security is implemented, the phone

makes a TLS connection. Otherwise, it makes a non-secure

TCP connection.

If the phone was manually added to the database,

Cisco Unified Communications Manager identifies the

phone. If the phone was not manually added to the database

and auto-registration is enabled in

Cisco Unified Communications Manager, the phone

attempts to auto-register itself in the

Adding Phones with Auto-Registration

By enabling auto-registration before you begin installing phones, you can:

•

Automatically add a Cisco Unified IP Phone to the Cisco Unified Communications Manager

database when you physically connect the phone to your IP telephony network. During

auto-registration, Cisco Unified Communications Manager assigns the next available sequential

directory number to the phone.

•

Add phones without first gathering MAC addresses from the phones.

Quickly enter phones into the Cisco Unified Communications Manager database and modify any

settings, such as the directory numbers, from Cisco Unified Communications Manager.

•

Move auto-registered phones to new locations and assign them to different device pools without

affecting their directory numbers.

Note

You should 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 B A T ”

section on page 2-10.

In some cases, you might not want to use auto-registration: for example, if you want to assign a specific

directory number to the phone or if you plan to implement authentication or encryption, as described in

Cisco Unified Communications Manager Security Guide. For information about enabling

auto-registration, refer to “Enabling Auto-Registration” in Cisco Unified Communications Manager

Administration Guide.

Note

Cisco Unified Communications Manager automatically disables auto-registration if you configure the

cluster-wide security mode for authentication and encryption through the Cisco CTL client.

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network

Adding Phones to the Cisco Unified Communications Manager Database

Adding Phones with Auto-Registration and TAPS

TAPS, the Tool for Auto-Registered Phones Support, works with the Bulk Administration Tool (BAT) to

update a batch of phones that were already added to the Cisco Unified Communications Manager

database with dummy MAC addresses. You use TAPS to update MAC addresses and download

pre-defined configurations for phones.

You can add phones with auto-registration and TAPS without first gathering MAC addresses from

phones.

Note

You should 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 2-10.

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 Communications Manager Administration with the correct MAC

address.

Auto-registration must be enabled in Cisco Unified Communications Manager Administration

(System > Cisco Unified CM) for TAPS to function.

Note

Cisco Unified Communications Manager automatically disables auto-registration if you configure the

cluster-wide security mode for authentication and encryption through the Cisco CTL client.

•

Working Voice over IP (VoIP) Network:

–

VoIP configured on your Cisco routers and gateways

Cisco Unified Communications Manager installed in your network and configured to handle

call processing

•

IP network that supports DHCP or manual assignment of IP address, gateway, and subnet mask

The Cisco Unified IP Phone displays the date and time from Cisco Unified Communications Manager.

If the Cisco Unified Communications Manager server is located in a different time zone than the phones,

the phones will not display the correct local time.

Cisco Unified Communications Manager Configuration

The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call

processing. Refer to Cisco Unified Communications Manager Administration Guide or context-sensitive

help in the Cisco Unified Communications Manager application to ensure that

Cisco Unified Communications Manager is set up properly to manage the phone and to properly route

and process calls.

If you plan to use auto-registration, verify that it is enabled and properly configured in

Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7960G and 7940G Components

Network and Access Ports

The back of the Cisco Unified IP Phones 7960G and 7940G have two RJ-45 ports labelled 10/100 SW

and 10/100 PC. Each port supports 10/100 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 Mbps connections. On both the network port and access port, use full-duplex mode to avoid

collisions.

Use the 10/100 SW port to connect the phone to the network. You must use a straight-through cable on

these ports. The phone can also obtain inline power from the Cisco Catalyst switch over these

connections. See the “Providing Power to the Cisco Unified IP Phone” section on page 2-3 for details.

Use the 10/100 PC 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.

To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port

on the back of the phone.

Speakerphone

By default, the speakerphone is enabled on Cisco Unified IP Phones.

You can disable the speakerphone through the Cisco Unified Communications Manager Administration

application. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone

Configuration window for the phone, Product Specific Configuration area, check the Disable

Speakerphone check box.

Headset

Although Cisco Systems performs 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.

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 recommends the use of good quality external devices, for example, 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

or echo may still occur. An audible hum or buzz may be heard by either the remote party or by both the

remote party and the Cisco Unified IP Phone user. Humming or buzzing sounds can be caused by a range

of outside sources; for example, electric lights, electric motors, or large PC monitors. See Using External

Devices with Y o ur Cisco Unified IP Phone, page 3-4, for more information.

Note

In some cases, hum may be reduced or eliminated by using a local power cube or power injector.

Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7960G and 7940G Components

These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are

deployed means that there is not a single headset solution that is optimal for all environments.

Cisco recommends that customers test headsets in their intended environment to determine performance

before making a purchasing decision and deploying en masse.

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 to the party on the far end. Sound quality is subjective and Cisco cannot guarantee

the performance of any headsets. However, a variety of headsets from leading headset manufacturers

have been reported to perform well with Cisco Unified IP Phones. See manufacturer’s sites for details.

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 Communications Manager Administration

application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified Communications Manager Administration, choose Device >

Phone and locate the phone that you want to modify. In the Phone Configuration window for the phone,

Product Specific Configuration area, check the Disable Speakerphone and Headset check box.

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 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.
