Obtaining Technical Assistance
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•
•
•
Priority level 4 (P4)—You need information or assistance concerning Cisco
product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network
functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded,
affecting significant aspects of business operations. No workaround is
available.
•
Priority level 1 (P1)—Your production network is down, and a critical impact
to business operations will occur if service is not restored quickly. No
workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and
the conditions of service contracts, when applicable.

Understanding How the Cisco IP Phone Interacts with the Cisco Catalyst
Family of Switches, page 2-2
Understanding How the Cisco IP Phone Interacts with
Cisco CallManager
Cisco CallManager is an open and industry-standard call processing system.
Cisco CallManager software runs on a Windows 2000 server and sets up and tears
down calls between phones, integrating traditional PBX functionality with the
corporate IP network. Cisco CallManager manages the components of the IP
telephony system—the phones, access gateways, and the resources necessary for
such features as call conferencing and route planning.
For information about configuring Cisco CallManager to work with the IP
devices described in this chapter, refer to the Cisco CallManager Administration
Guide and the Cisco CallManager System Guide.
Understanding How the Cisco IP Phone Interacts with the
Cisco Catalyst Family of Switches
Cisco IP Phones have an internal Ethernet switch, enabling them to switch
incoming traffic to the phone, the access port, or to the network port (see the
“Connecting to the Network” section on page 2-6 for details).
If a computer is connected to the access port, data packets traveling to and from
the computer, and to and from the phone, share the same physical link to the
switch and the same port on the switch.

Chapter 2 Preparing to Install the Cisco IP Phone on Your Network
Understanding the Phone Startup Process
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.
You can resolve these issues by isolating the voice traffic onto a separate VLAN
on each of the ports connected to a phone. The switch port configured for
connecting a phone would have separate VLANs configured for carrying:
•
•
Voice traffic to and from the IP phone (auxiliary VLAN)
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 more information, refer to the documentation included with the
Cisco Catalyst switch.

The Cisco IP Phone 7910 does not have an access port. If you require an access
port on this phone model, use the Cisco IP Phone 7910+SW instead.

Obtaining Power from the Switch
You can connect the Cisco IP Phone to a Cisco Catalyst switch with one of the
modules that provides power to the phone (WS-X6348-RJ45V). See the
“Providing Power to the Cisco IP Phone” section on page 2-7 for details.
If you use this optional configuration, the phone receives phantom power and
powers up when you connect the Cisco IP Phone to the switch. The phone then
sends Cisco Discovery Protocol (CDP) notifications to the switch indicating it is
ready to receive CDP packets and indicating the power requirement for the phone.
The switch allocates power and sends it over the network cable.
Loading the Stored Phone Image
The Cisco IP Phone has non-volatile Flash memory in which it stores firmware
images and user-defined preferences. At startup, the phone runs a bootstrap loader
that loads a phone image stored in Flash memory. Using this image, the phone
initializes its software and hardware.
Configuring VLAN
If the Cisco IP Phone is connected to a Cisco Catalyst switch, the switch next
informs the phone of the voice VLAN defined on the switch. The phone needs to
know its VLAN membership before it can proceed with the Dynamic Host
Configuration Protocol (DHCP) request for an IP address.
Obtaining an IP Address
If the Cisco IP Phone is using DHCP to obtain an IP address, the phone queries
the DHCP server to obtain one. If you are not using DHCP in your network, you
must assign static IP addresses to each phone locally.

Chapter 2 Preparing to Install the Cisco IP Phone on Your Network
Understanding the Phone Startup Process
Accessing TFTP Server
In addition to assigning an IP address, the DHCP server also directs the
Cisco 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 goes to
the TFTP server directly.
Requesting the Configuration File
The TFTP server has configuration files (.cnf file format) for telephony devices,
which define parameters for connecting to Cisco CallManager. In general, any
time you make a change in Cisco CallManager that requires the phone (device) to
be reset, a change has been made to the phone's configuration file.
If a phone has an XML-compatible load, it requests a .XMLDefault.cnf.xml
format configuration file; otherwise, it requests a .cnf file.
If you have enabled auto-registration in Cisco CallManager, the phones access a
default configuration file (sepdefault.cnf.xml) from the TFTP server. If you have
manually entered the phones into the Cisco CallManager database, the phone
accesses a .cnf.xml file corresponding to its device name.
The .cnf.xml file also contains the information telling the phone which image load
it should be running. If this image load differs from the one currently loaded on
the phone, the phone contacts the TFTP server to request the new image file,
which is stored as a .bin file.
Contacting Cisco CallManager
The configuration file defines how the Cisco IP Phone communicates with
Cisco CallManager. After obtaining the file from the TFTP server, the phone next
attempts to make a TCP connection to the highest priority Cisco CallManager on
the list.
If the phone was manually added to the database, Cisco CallManager identifies
the phone. If the phone was not manually added to the database and
auto-registration is enabled in Cisco CallManager, the phone attempts to
auto-register itself in the Cisco CallManager database.

Guidelines for Configuring Ports on Cisco IP Phones
Cisco CallManager informs devices using .cnf format configuration files of their
load ID. Devices using .xml format configuration files receive the load ID in the
configuration file.
Cisco IP Phones include ports for connecting the phones to the network, for
providing power to the phones, and for adding headsets to the phones. These
sections provide tips for configuring these ports:
•
•
•
Connecting to the Network, page 2-6
Providing Power to the Cisco IP Phone, page 2-7
Configuring the Handset, Headset, and Speakerphone, page 2-8
Connecting to the Network
The Cisco IP Phones have two RJ-45 ports labelled “network” and “access.” Each
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
use full-duplex mode to avoid collisions.
Note
The Cisco IP Phone 7910 does not have an access port. If you require an access
port on this phone model, use the Cisco IP Phone 7910+SW instead.
Using the Network Port
Use the 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
the Cisco Catalyst switch over this connection. See the “Providing Power to the
Cisco IP Phone” section on page 2-7 for details.

Guidelines for Configuring Ports on Cisco IP Phones
Using the Access Port
Use the access port to connect a network device, such as a computer, to the phone.
You must use a straight-through cable on this port.
Providing Power to the Cisco IP Phone
You can power a Cisco IP Phone from an external power supply, from a switch
port, or from a power source between the phone and the switch.
The Cisco IP Phone can be powered by the following sources:
•
External power source—optional Cisco AC adapter and power cord for
connecting to a standard wall receptacle.
•
WS-X6348-RJ45V 10/100 switching module—inline power provider to the
Cisco IP Phone when connected to a Catalyst 6000 family 10/100BaseTX
switching module.
This module sends power on pins 1 & 2 and 3 & 6, which are also used to
transmit Ethernet signals. Before the switch sends power, it tests for the
presence of a Cisco IP Phone, avoiding damage to other Ethernet devices.
Note
Only the network port supports inline power from the Cisco
Catalyst switches.
•
WS-PWR-PANEL—power patch panel that allows the Cisco IP Phone to be
connected to existing Catalyst 4000, 5000, and 6000 family 10/100BaseTX
switching modules.
This module sends power on pins 4, 5, 7, & 8, which are not used for Ethernet
signaling. Like the inline power, the power patch panel also attempts to verify
that the attached device is a Cisco IP Phone before providing power.
Power Source Design
The phone and switch automatically determine which power source the phone
uses. If the power has to be switched to a different source, the phone user will
experience different results based on which power source is being used by the
phone.

Chapter 2 Preparing to Install the Cisco IP Phone on Your Network
Guidelines for Configuring Ports on Cisco IP Phones
Use the following information to choose a power source for the phone:
•
If you plug a phone into the optional power supply before plugging it into the
network, the phone is powered by the power supply.
•
If you then unplug the phone from the power supply, the phone resets. If the
switch port is configured for 10/100 Mbps, the switch recognizes the loss of
power and brings the phone back up.
•
•
If the switch port is configured for 10 Mbps only, then you must unplug the
network connection and plug it back into the phone for the switch to
recognize the phone’s loss of power.
If, however, you plugged the network connection into the phone before you
plugged in the power cord, the phone receives power through the switch, and
unplugging the power cord will not bring down the phone. If the switch
reboots, the phone will then be powered by the power cord.
Redundancy Feature
For redundancy, you can use the Cisco AC adapter even if you are using inline
power from the Cisco Catalyst switches. The Cisco IP Phone can share the power
load being used from the inline power and external power source. If either the
inline power or the external power goes down, the phone can switch entirely to
the other power source.
To use this redundancy feature:
1. Set the inline power mode to auto on the Cisco Catalyst switch.
2. Connect the unpowered Cisco IP Phone to the network.
3. Connect the external power supply to the phone after the phone powers up.
Configuring the Handset, Headset, and Speakerphone
Cisco IP Phones enable you to connect a headset to them or use the built-in
speakerphone to make calls rather than the standard handset. These sections

disable it on Cisco IP Phone models 7960 and 7940.
To disable the speakerphone on these models, choose Device > Phone from the
Cisco CallManager Administration application and locate the phone you want to
modify. Check the Disable Speakerphone check box to disable the speakerphone
for the phone you have selected.
Adding Phones to the Cisco CallManager Database
Before installing any Cisco IP phones, you must make decisions about how you
want the phones to be added to the Cisco CallManager database. Because
Cisco CallManager handles call processing in the network, this is a critical step.
You can add phones to the Cisco CallManager database automatically using
auto-registration, manually using the Cisco CallManager Administration
device name, registration status, and the IP address of the Cisco CallManager to
which the device is registered.

Adding Phones to the Cisco CallManager Database
Tip
To get help using the Cisco CallManager application, access context-sensitive
help by choosing Help > For this screen from the main menu bar. For
complete instructions and conceptual information, refer to the
Cisco CallManager Administration Guide and the Cisco CallManager System
Guide.
Using Auto-Registration
Use auto-registration if you want Cisco CallManager to assign directory numbers
automatically to new phones as they connect to the IP telephony network. Once a
phone has auto-registered, you can move it to a new location and assign it to a
different device pool without affecting its directory number.
With auto-registration enabled, Cisco CallManager begins the automatic startup
process to obtain a directory number as soon as you connect the Cisco IP Phone
to the network. During auto-registration, Cisco CallManager automatically
assigns the next available sequential directory number to the phone.
Use auto-registration to quickly get all phones into the Cisco CallManager
database. You can then modify any settings, such as the directory numbers, from
Cisco CallManager. If you do not use auto-registration, you must manually add
phones to the Cisco CallManager database or use the Bulk Administration Tool
(BAT).
Use the following procedure as a starting point to enable auto-registration using
the Cisco CallManager Administration application. For additional information,
access context-sensitive help from the application or refer to Cisco CallManager
documentation.

Adding Users to Cisco CallManager
Adding Users to Cisco CallManager
Cisco CallManager Administration allows you to display and maintain
information about users on the network.
You must configure features to allow users to perform the following actions:
•
Access the corporate directory and other customized directories from a
Cisco IP Phone
•
•
Set up their own speed dial and call forwarding numbers
Subscribe to services that are accessible from a Cisco IP Phone
To set up these features, you must first add users to Cisco CallManager. Choose
either of the following methods:
•
To add users individually, use the Cisco CallManager Administration
application and select User >Add a New User.
Refer to the Cisco CallManager Administration Guide, the Cisco
CallManager System Guide, or context-sensitive help in the application for
details.
•
To add users in batches, use the Bulk Administration Tool. This method also
enables you to set an identical default password for all users.
Refer to the Bulk Administration Tool User Guide for details.
Modifying Phone Button Templates
Although the Cisco IP Phones support similar features, each phone model can
implement these features differently. Modify phone button templates to assign
features to phone buttons and to customize features for a phone model.
Ideally, you can modify templates before registering phones on the network.
Proceeding in this order allows you to access customized phone button template
options from the Cisco CallManager Administration application during
registration.
To modify a phone button template, open the Cisco CallManager Administration
application and select Device > Phone Button Template. Refer to the
Cisco CallManager Administration Guide, the Cisco CallManager System Guide,
or context-sensitive help in the application for details.

Cisco IP Phone 7910
The default phone button template for the Cisco IP Phone 7910
(named Default 7910) uses button 1 for message waiting, button 2 for
conference, button 3 for forwarding, buttons 4 and 5 for speed dial,
and button 6 for redial.
The Cisco IP Phone 7910 has fixed buttons for Line, Hold, Transfer,
and Settings.
Updating Button Labels
If you change the button assignments on the Cisco IP Phone 7910, you can also
update their corresponding labels. The Cisco IP Phone 7910 ships with extra
mylar labels on a perforated sheet. After printing the labels, you can easily
remove them from this sheet. These label sheets have different textures—one
smooth side and one textured side; the textured side is labeled “front.” This is the
side that users contact when pressing the buttons. The type of printing method
used determines the side to print on. To avoid ink rubbing off on users’ fingers,
choose a printing method that prints on the smooth side of the labels.
Use these specifications to print on the labels:
•
Text size—10 point (on a PC-compatible computer) or 12 point (on a
Macintosh-compatible computer)
•
•
•
Text font—Univers 65 bold oblique
Text color—PMS 413C
Text position—2.533 mm above the button hole openings

Configuring Corporate Directories
Configuring Corporate Directories
Cisco IP Phone models 7960 and 7940 can store a directory of employee names
and phone numbers. Although you access the directory from the IP Phone, you
must configure the directory before users can access it. To use the corporate
directory, you must have users entered into a Lightweight Directory Access
Protocol (LDAP) directory configured with Cisco CallManager.
To set up these features, open Cisco CallManager and select User > Global
Directory. Refer to the Cisco CallManager Administration Guide, the
Cisco CallManager System Guide, or context-sensitive help in the
Cisco CallManager Administration application for details.
Setting Up User Services
The Cisco IP Phone models 7960 and 7940 allow users to access specific
information services, such as local movie times, stock quotes, weather reports,
and so on. Although users access these services by pressing the Services button
to display a services menu on the Cisco IP Phone, you must first configure the
services to which users can subscribe.
In summary:
•
System administrators configure available services using the
Cisco CallManager Administration application.
•
Users subscribe to services using the Cisco IP Phone User Options
application. This web-based application provides a graphic user interface
(GUI) for limited, end-user configuration of IP Phone applications.
Before setting up services, gather the URL addresses for the sites you want to set
up and verify that users can access those sites from your corporate IP telephony
network.
To set up these features, open the Cisco CallManager Administration application
and select Feature > Cisco IP Phone Services. Refer to the Cisco CallManager
Administration Guide, the Cisco CallManager System Guide, or context-sensitive
help in the Cisco CallManager Administration application for details.

instructs users to direct some questions to a system administrator. To assist
users, consider distributing an E-mail or memo identifying yourself or your
network team. Provide contact information.
•
Provide end users with the following information about the Cisco IP Phone
User Options web-based application:
–
The URL required to access the application
http://<serverName>/CCMUser/, where <serverName> is the host on
which the web server is installed.
–
A user ID and default password needed to access the application
These settings correspond to the values you entered when you added the
user to Cisco CallManager.
–
–
A brief description of what a web-based, graphic user interface
application is, and how it is accessed with a Web browser.
Outline the tasks that users can expect to accomplish with the

G.711 u-law, G.711 A-law, or Link16k).
RxSize—Size of voice packets (in milliseconds) in the receiving voice stream
(RTP streaming audio).
RxCnt—Number of RTP voice packets received since voice stream was
opened (which is not necessarily identical to those received since the call
began because the call might have been placed on hold).
•
•
•
TxType—Type of voice stream transmitted (RTP streaming audio) (G.729,
G.711 u-law, G.711 A-law, or Link16k).
TxSize—Size of voice packets (in milliseconds) in the transmitting voice
stream.

•
The RxType/TxType indicates which codec is being used for the call between
this phone and the other device. If they do not match, verify that the other
device supports the codec conversation or that a transcoder is in place to
support the service.
•
•
The size of the sound samples (RxSize/TxSize) should match on both
devices.
If you are experiencing gaps in your voice calls, check the AvgJtr and MaxJtr
values. A large variance between the two values might indicate a problem
with jitter on the network or periodic high rate of network activity.

Chapter 7 Troubleshooting the Cisco IP Phone
Resolving Startup Problems
Symptom: Cisco IP Phone Does Not Start Up and LCD Screen
Does Not Display
If you connect a Cisco IP Phone into the network port, the LEDs should light up
and messages should appear on the LCD display (see the “Verifying the Phone
Startup Process” section on page 3-9 for information on the normal startup
process). If the phone does not proceed through this normal startup process, you
must determine if the phone is functional or if anything else in the configuration
is causing the phone to not start up properly.
To determine whether the phone is functional, you must eliminate any other
potential problems, such as faulty cables, network outages, lack of power, and so
on. Follow these suggestions to systematically eliminate these other causes.
Procedure
Step 1
To verify that the network port is functional:
a. Exchange the Ethernet cables with cables you know are functional.
b. Disconnect a functioning Cisco IP Phone from another port and connect it to
this network port to verify the port is active.
c. Connect the Cisco IP Phone that will not start up to a different, known good
network port.
d. Connect the Cisco IP Phone that will not start up directly to the port on the
switch, eliminating the patch panel connection in the office.
Step 2
Step 3
To verify that the phone is receiving power:
a. Verify that the electrical outlet is functional.
b. If you are using in-line power, use the external power supply instead.
c. If you are using the external power supply, switch with a unit you know to be
functional.
If after attempting these solutions, the LCD screen on the Cisco IP Phone persists
in not displaying any characters for at least 5 minutes, contact a Cisco technical
support representative for additional assistance.

Chapter 7 Troubleshooting the Cisco IP Phone
Resolving Startup Problems
Registering the Phone with Cisco CallManager
Registration with a Cisco CallManager server can only be successful if the phone
has been added to the server or if auto-registration is enabled. Review the
information and procedures in the “Adding Phones to the Cisco CallManager
To verify that the phone is in the Cisco CallManager database, use Device > Find
from Cisco CallManager to search for the phone based on its MAC Address.
Verify the MAC address to search for by pressing settings > Network
Configuration > MAC address on the phone.
If the phone is already in the Cisco CallManager database, its configuration file
might be damaged. Refer to the “Creating a New Configuration File” section on
page 7-21 for assistance.
Checking Network Connectivity
If the network is down between the phone and the TFTP server or
Cisco CallManager, the phone cannot start up properly. Ensure that the network
is currently up-and-running.
Verifying TFTP Server Settings
The Cisco IP Phone uses the TFTP server setting (settings > Network
Configuration > TFTP Server 1) to identify the Cisco CallManager server. If
this setting is incorrect, the Cisco IP Phone might continually cycle while
attempting to contact the identified TFTP Server.
If you have assigned a static IP address to the phone, you must manually enter this
setting. Refer to the “Configuring IP Settings” section on page 5-14.
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. See
Configuring Windows 2000 DHCP Server for Cisco Call Manager on Cisco.com:
http://www.cisco.com/warp/customer/788/AVVID/win2000_dhcp.html
You can also enable the phone to use an alternate TFTP server (settings >
Network Configuration > Alternate TFTP Server). This is particularly useful
if this phone was recently moved from a different location, such as a test lab to a
production network.

Chapter 7 Troubleshooting the Cisco IP Phone
Resolving Startup Problems
You must unlock the network settings before you can assign an alternate TFTP
server (see “Accessing the Network Configuration Settings” section on page 5-2).
Verifying IP Addressing and Routing
You should verify the IP addressing and routing settings on the IP 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 IP Phone, press settings > Network Configuration and check for
the following problems:
•
DHCP Server—has no address
If you have assigned a static IP address to the phone, you do not need to enter
a value here. However, if you are using a DHCP server, this field must have
a value. If it does not, check your IP routing and VLAN configuration. See
Troubleshooting Switch Port Problems on Cisco.com:
http://www.cisco.com/warp/customer/473/53.shtml
•
IP address, subnet mask, or default router—have no addresses
If you have assigned a static IP address to the phone, you must manually enter
these settings. Refer to the “Configuring IP Settings” section on page 5-14.
If you are using DHCP, check the IP addresses distributed by your DHCP server.
See Understanding and Troubleshooting DHCP in Catalyst Switch or Enterprise
Networks on Cisco.com: http://www.cisco.com/warp/customer/473/100.html#41
Verifying DNS Settings
If you are using DNS to refer to the TFTP server or Cisco CallManager, you must
ensure you have specified a DNS server (settings > Network Configuration >
DNS Server 1). You should also verify that you have a CNAME entry in the DNS
server for the TFTP server and Cisco CallManager system.
You must also ensure that DNS is configured to do reverse look-ups. The default
setting on Windows2000 is to perform forward-only look-ups.

1, 2, 3, 4. The Cisco IP Phone attempts to open a TCP connection to all the
Cisco CallManager servers that are part of the assigned CallManager group. If
none of these fields have IP addresses or state “Active” or “Standby”, the phone
is not properly registered with Cisco CallManager. Refer to the “Registering the
Phone with Cisco CallManager” section on page 7-18 for tips on resolving this
problem.
Cisco CallManager and TFTP Services Are Not Running
If the Cisco CallManager or TFTP services are not running, phones might not be
able to start up properly. However, in this case, it is likely that you are
experiencing a system-wide failure. Rather than being isolated to one phone that
is experiencing problems, in this situation many or all phones and other devices
are not able to start up properly.
If the Cisco 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.
Procedure
Step 1
From the Cisco CallManager Administration window, choose Application >
Cisco CallManager Serviceability.
Step 2
Step 3
Choose Tools > Control Center.
From the Servers column, choose the primary Cisco CallManager server.
The window 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.
Step 4
If a service has stopped, click the Start button.
The Service Status symbol changes from a square to an arrow.

Chapter 7 Troubleshooting the Cisco IP Phone
Resolving Startup Problems
Creating a New Configuration File
If you continue to have problems with a particular phone, despite all attempts at
resolution, the configuration file might be corrupted. You can manually create a
new configuration file by following the procedure below.
Procedure
Step 1
From Cisco CallManager, select Device > Phone > Find to locate the phone
experiencing problems.
Step 2
Step 3
Choose Delete to remove the phone from the Cisco CallManager database.
Search the hard drive of the Cisco CallManager server for files named
SEP*.cnf.xml. This file should be in a folder containing the configuration files for
all the registered phones.
Step 4
Make a copy of a configuration file for a functional phone of the same type as the
problematic phone. For example, if the phone experiencing problems is a Cisco
IP Phone 7960, make a copy of a configuration file for another phone of this
model.
Rename this to match the name of the configuration file for the problematic
phone.
Use the convention SEP<MAC address>.cnf.xml, where <MAC address> is the
MAC address for the deleted phone.
Step 6
Step 7
Replace the old configuration file with the new one you created.
Add the phone to Cisco CallManager database. See the “Adding Phones
Manually” section on page 2-12 for details.
Step 8
Power cycle the phone.
Symptom: Cisco IP Phone Resetting
Once a Cisco IP Phone has properly started up and registered with
Cisco CallManager, you can reset it, forcing it to go through the startup process.
At times, you might want to intentionally do this. For example, if you want to

Verifying Physical Connection
Verify that the Ethernet connection to which the Cisco IP Phone is connected is
up-and-running. For example, check if the particular port or switch to which the
phone is connected is down.
Identifying Intermittent Network Outages
Intermittent network outages affect data and voice traffic differently. Your
network might have been experiencing intermittent outages without detection, but
data traffic can resend lost packets and verify 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.
Therefore, if you are experiencing problems with the voice network, you should
investigate whether an existing problem is simply being exposed at this point.

Resolving Startup Problems
Verifying DHCP Settings
This procedure can help you verify if the phone has been properly configured to
use DHCP.
Procedure
Step 1
Verify that you have properly configured the phone to use DHCP. See the
“Modifying DHCP Settings” section on page 5-9 for details.
Step 2
Step 3
Verify that the DHCP server has been set up properly.
Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.
Note, however, that Cisco IP Phones send messages with request type 151 to
renew their DHCP address leases. If the DHCP server expects messages with
request type 150, the lease is denied, forcing the phone to restart and request a
new 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 “Configuring IP Settings” section on page 5-14.
Verifying Voice VLAN Configuration
If the Cisco 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 “Understanding How the Cisco IP Phone Interacts with the
Cisco Catalyst Family of Switches” section on page 2-2 for more details.
Verifying that the Phones Have Not Been Intentionally Reset
If you are not the only administrator with access to Cisco CallManager, you
should verify that no one else has intentionally reset the phones.

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 prevent this, wait 10 seconds or longer
after unplugging the cable from the phone. This
gives the switch enough time to recognize that there

Phone resetting
The phone resets when it loses contact with the
Cisco CallManager software. This lost connection can be due to
any network connectivity disruption, including cable breaks,
switch outages, and switch reboots.
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
