Supported Networking Protocols
Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice
communication. The following table provides an overview of the networking protocols that the Cisco Unified
SIP Phone 3905 support.
Table 1: Supported Networking Protocols on the Cisco Unified IP Phone
Cisco Discovery
Protocol (CDP)
CDP is a device-discovery protocol
that runs on all Cisco-manufactured
equipment.
Using CDP, a device can advertise
its existence to other devices and
receive information about other
devices in the network.
Usage NotesPurposeNetworking Protocol
The Cisco Unified IP Phone uses CDP to
communicate information such as auxiliary
VLAN ID, per port power management
details, and Quality of Service (QoS)
configuration information with the Cisco
Catalyst switch.
DHCP dynamically allocates and
assigns an IP address to network
devices.
DHCP enables you to connect an IP
phone into the network and have the
phone become operational without
your needing to manually assign an
IP address or to configure additional
network parameters.
DHCP is enabled by default. If disabled, you
must manually configure the IP address,
subnet mask, gateway, and a TFTP server on
each phone locally.
Cisco recommends that you use DHCP
custom option 150. With this method, you
configure the TFTP server IP address as the
option value. For additional supported DHCP
configurations, go to the “Dynamic Host
Configuration Protocol” chapter and the
“Cisco TFTP” chapter in the Cisco Unified
Communications Manager System Guide.
Note
If you cannot use option 150, you
may try using DHCP option 66.

Supported Networking Protocols
Cisco Unified IP Phone
Usage NotesPurposeNetworking Protocol
Hypertext Transfer
Protocol (HTTP)
IEEE 802.1X
Internet Protocol (IP)
HTTP is the standard way of
transferring information and moving
documents across the Internet and
the web.
The IEEE 802.1X standard defines
a client-server-based access control
and authentication protocol that
restricts unauthorized clients from
connecting to a LAN through
publicly accessible ports.
Until the client is authenticated,
802.1X access control allows only
Extensible Authentication Protocol
over LAN (EAPOL) traffic through
the port to which the client is
connected. After authentication is
successful, normal traffic can pass
through the port.
IP is a messaging protocol that
addresses and sends packets across
the network.
Cisco Unified IP Phones use HTTP for
troubleshooting purposes.
The Cisco Unified IP Phone implements the
IEEE 802.1X standard by providing support
for the MD5 authentication method.
When 802.1X authentication is enabled on
the phone, you should disable the voice
VLAN. See the Security Configuration
Menu, on page 44 for additional
information.
To communicate using IP, network devices
must have an assigned IP address, subnet,
and gateway.
IP addresses, subnets, and gateways
identifications are automatically assigned if
you are using the Cisco Unified IP Phone
with Dynamic Host Configuration Protocol
(DHCP). If you are not using DHCP, you
must manually assign these properties to each
phone locally.
Cisco Unified IP Phones use the RTP
protocol to send and receive real-time voice
traffic from other phones and gateways.
RTCP is disabled by default, but you can
enable it on a per phone basis by using
Cisco Unified Communications Manager.
Session Initiation
Protocol (SIP)
Transmission Control
Protocol (TCP)
SIP is the Internet Engineering Task
Force (IETF) standard for
multimedia conferencing over IP.
SIP is an ASCII-based
application-layer control protocol
(defined in RFC 3261) that can be
used to establish, maintain, and
terminate calls between two or more
endpoints.
TCP is a connection-oriented
transport protocol.
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.
Cisco Unified IP Phones use TCP to connect
to Cisco Unified Communications Manager.
Cisco Unified IP Communications Product Interactions, on page 21
Phone Startup Process, on page 25
TFTP allows you to transfer files
over the network.
On the Cisco Unified IP Phone,
TFTP enables you to obtain a
configuration file specific to the
phone type.
UDP is a connectionless messaging
protocol for delivery of data packets.
TFTP requires a TFTP server in your
network, which can be automatically
identified from the DHCP server. If you want
a phone to use a TFTP server other than the
one specified by the DHCP server, you must
manually assign the IP address of the TFTP
server by using the Network Configuration
menu on the phone.
For more information, go to the “Cisco TFTP”
chapter in the Cisco Unified CommunicationsManager System Guide.
Cisco Unified IP Phones transmit and receive
RTP streams, which utilize UDP.
Cisco Unified SIP Phone 3905 Supported Features
Cisco Unified IP Phones function much like a digital business phone, allowing you to place and receive phone
calls. In addition to traditional telephony features, the Cisco Unified IP Phone includes features that enable
you to administer and monitor the phone as a network device.
Feature Overview
Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring,
redialing, conference calling, and voice messaging system access. Cisco Unified IP phones also provide a
variety of other features.
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, subnet information, and so on.
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.

802.1X authentication
The Cisco Unified IP Phones support 802.1X authentication.
Overview
Cisco Unified IP Phones and Cisco Catalyst switches traditionally use Cisco Discovery Protocol (CDP) to
identify each other and determine parameters such as VLAN allocation and inline power requirements. CDP
does not identify locally attached workstations. Cisco Unified IP Phones provide an EAPOL pass-through
mechanism. This mechanism allows a workstation attached to the Cisco Unified IP Phone to pass EAPOL
messages to the 802.1X authenticator at the LAN switch. The pass-through mechanism ensures that the IP
phone does not act as the LAN switch to authenticate a data endpoint before accessing the network.
Cisco Unified IP Phones also provide a proxy EAPOL Logoff mechanism. In the event that the locally attached
PC disconnects from the IP phone, the LAN switch does 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
G729A/AB: 3.7
•
Version of the Cisco-proprietary algorithm used to calculate the MOS
LQK scores.
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.
Cisco Unified IP Phones also contain an 802.1X supplicant. This supplicant allows network administrators
to control the connectivity of IP phones to the LAN switch ports. The current release of the phone 802.1X
supplicant uses the EAP-FAST, EAP-TLS, and EAP-MD5 options for network 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 authenticates 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. After the
exchange completes, the switch grants or denies the phone access to the network.
Cisco Unified IP Phone
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.
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:
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. 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.
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 information and a
checklist for setting up and configuring a Cisco IP telephony network, go to the “System Configuration
Overview” chapter in Cisco Unified Communications Manager System Guide.
After you have set up the IP telephony system and configured system-wide features in Cisco Unified
Communications Manager, you can add IP phones to the system.

Cisco Unified IP Communications Product Interactions
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.
Cisco Unified IP Phone and Cisco Unified Communications Manager Interaction
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 features such as call conferencing and route planning. Cisco Unified Communications Manager also
provides:
Firmware for phones
•
Configuration file via TFTP service
•
Phone registration

Cisco Unified SIP Phone 3905 and VLAN Interaction
The Cisco Unified SIP Phone 3905 has an internal Ethernet switch, enabling 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 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.
For more information, refer to the documentation included with a Cisco switch. You can also access switch
information at this URL:
The Cisco Unified SIP Phone 3905 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.
Power Guidelines
The following table provides guidelines for powering the Cisco Unified SIP Phone 3905.

Your access to emergency service through the phone requires the phone to receive power. If an interruption
in the power supply occurs, Service and Emergency Calling Service dialing do not function until power is
restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before
you can use the Service or Emergency Calling Service dialing.
The Cisco Unified SIP Phone 3905 supports IEEE 802.3af Class 1 power

Additional Information About Power
The documents in the following table provide more information on the following topics:
Cisco switches that work with Cisco Unified IP Phones
•
Cisco IOS releases that support bidirectional power negotiation
Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco
Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications
Manager that requires the phone to be reset, a change is automatically made to the phone configuration file.
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.
If you configure security-related settings in Cisco Unified Communications Manager Administration, the
phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you
must configure it for encryption. For more information, see the “Configuring Encrypted Phone Configuration
Files” chapter in Cisco Unified Communications Manager Security Guide. A phone requests a configuration
file whenever it resets and registers with Cisco Unified Communications Manager.
A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when the
following conditions exist:
Configuration Files
You have enabled auto-registration in Cisco Unified Communications Manager
•
The phone has not been added to the Cisco Unified Communications Manager 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 Communications
Manager database, the phone registration request will be rejected.
For more information on phone configuration settings, see the “Cisco Unified IP Phone Configuration” chapter
in the Cisco Unified Communications Manager Administration Guide.
Phone Startup Process
When connecting to the VoIP network, the Cisco Unified SIP Phone 3905 go through a standard startup
process that is described in the following table. Depending on your specific network configuration, not all of
these steps may occur on your Cisco Unified IP Phone.
Procedure
Step 1
Obtain power from the Switch. If a phone is not using external power, the switch provides in-line power
through the Ethernet cable attached to the phone.
For more information, see Cisco Unified Communications Manager Phone Addition Methods, on page 26
and Startup Problems, on page 79.
Step 2
Step 3
Configure the VLAN. If the Cisco Unified 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.
For more information, see Configuration Menus, on page 35 and Startup Problems, on page 79.
Obtain an IP Address. If the Cisco Unified 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.
For more information, see Configuration Menus, on page 35 and Startup Problems, on page 79.
Cisco Unified IP Phone and Your Network
Step 4
Step 5
Step 6
Step 7
Access a TFTP Server. 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
For more information, see Configuration Menus, on page 35 and Startup Problems, on page 79.
Request the Configuration File. The TFTP server has configuration files, which define parameters for connecting
to Cisco Unified Communications Manager and other information for the phone.
For more information, see Cisco Unified Communications Manager Phone Addition Methods, on page 26
and Startup Problems, on page 79.
Load the Stored Phone Image. The Cisco Unified IP Phone has nonvolatile 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.
For more information, see Startup Problems, on page 79.
Contact 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 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 Cisco
Unified Communications Manager database.
For more information, see Startup Problems, on page 79.
You can also assign an alternative TFTP server to use instead of the one assigned by
DHCP.
Before installing the Cisco Unified IP phone, you must choose a method for adding phones to the
Cisco Unified Communications Manager database. Be aware that each phone type requires a fixed number
of device license units and the number of unit licenses that are available on the server may impact phone
registration. For more information on licensing, see the “Licenses for Phones” section in the Cisco UnifiedCommunications Manager System Guide.
The following table provides an overview of these methods for adding phones to the Cisco Unified
Communications Manager database.

Cisco Unified Communications Manager assigns the next available sequential directory number to the
phone.
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.
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).
Auto-registration is disabled by default. 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. For information about enabling
auto-registration, see the “Enabling Auto-Registration” section in the Cisco Unified Communications ManagerAdministration Guide.
You can add phones with auto-registration and TAPS, the Tool for Auto-Registered Phones Support, without
first gathering MAC addresses from phones.
TAPS 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. Use TAPS to update
MAC addresses and download pre-defined configurations for phones.
Cisco Unified IP Phone and Your Network
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).
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.
For more information, see the “Bulk Administration” chapter in Cisco Unified Communications ManagerAdministration Guide.
You can add phones individually to the Cisco Unified Communications Manager database by using
Cisco Unified Communications Manager Administration. To do so, you first need to obtain the MAC address
for each phone.
After you have collected MAC addresses, in Cisco Unified Communications Manager Administration, choose
Device > Phone and click Add New to begin.
For complete instructions and conceptual information about Cisco Unified Communications Manager, go to

After you install Cisco Unified IP Phones in your network, configure their network settings, and add them
to Cisco Unified Communications Manager, you must use the Cisco Unified Communications Manager
Administration application to configure telephony features, optionally modify phone templates, set up
services, and assign users.
This chapter provides an overview of these configuration and setup procedures. Cisco Unified Communications
Manager documentation provides detailed instructions for these procedures.
To list supported features for all phones or for a particular phone model on your Cisco Unified
Communications Manager, you can generate a Unified CM Phone Feature List report on Cisco Unified
Reporting.
For suggestions about how to provide users with information about features, and what information to provide,
see Internal Support Web Site, on page 97

CHAPTER 8
Startup Problems
After installing a Cisco Unified IP Phone into your network and adding it to Cisco Unified Communications
Manager, the phone should start up as described in the Phone Startup Verification, on page 34. If the phone
does not start up properly, see the following sections for troubleshooting information.
Cisco Unified IP Phone Does Not Go Through Normal Startup Process
Problem
When you connect a Cisco Unified IP Phone into the network port, the phone should go through its normal
startup process as described in Phone Startup Verification, on page 34.
Cause
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:
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.
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 the phone still does not start up properly, perform a factory reset of the phone. For instructions, see
•
the Perform Factory Reset, on page 92.
If after attempting these solutions, the phone still does not function, contact a Cisco technical support
representative for additional assistance.
Cisco Unified IP Phone Does Not Register with Cisco Unified Communications Manager
If the phone proceeds past the first stage of the startup process (all LED buttons on) but the phone is not
starting up properly. The phone cannot successfully start up unless it is connected to the Ethernet network
and it has registered with a Cisco Unified Communications Manager server.
In addition, problems with security may prevent the phone from starting up properly. See the General
Troubleshooting Information, on page 89 for more information.
Phone Displays Error Messages
Problem
Phone status message display errors during startup.
Solution
While 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 Device Logs, on page 71 for instructions about
accessing status messages.
Phone Cannot Connect to TFTP Server or to Cisco Unified Communications Manager
Problem
If the network is down between the phone and either the TFTP server or Cisco Unified Communications
Manager, the phone cannot start up properly.
Solution
Ensure that the network is currently running.
TFTP Server Settings
Problem
The TFTP server settings may not be correct.
Solution
Check the TFTP settings. See TFTP Settings, on page 87.
Startup Problems
IP Addressing and Routing
Problem
The IP addressing and routing fields may not be correctly configured.
Solution
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. See DHCP Setting Verification, on page 87.
Cisco CallManager and TFTP Services Are Not Running
Problem
If the Cisco CallManager or TFTP services are not running, phones may not be able to start up properly. In
such a situation, it is likely that you are experiencing a systemwide failure, and other phones and devices are
unable to start up properly.
Solution
If the Cisco CallManager service is not running, all devices on the network that rely on it to make phone calls
are affected. If the TFTP service is not running, many devices cannot start up successfully. For more
information, see Start Service, on page 87.
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.
Solution
Create a new phone configuration file. See Create New Configuration File, on page 88.
The phone is not registered with the Cisco Unified Communications Manager.
Solution
A Cisco Unified IP Phone can register with a Cisco Unified Communications Manager server only if the
phone has been added to the server or if auto-registration is enabled and if there is a sufficient number of unit
licenses. Review the information and procedures in the Cisco Unified Communications Manager Phone
Addition Methods, on page 26 to ensure that the phone has been added to the Cisco Unified Communications
Manager database.
To verify that the phone is in the Cisco Unified Communications Manager database, choose Device > Phone
> Find from Cisco Unified Communications Manager Administration to search for the phone based on its
MAC Address. For information about determining a MAC address, see the MAC Address for Cisco Unified
IP Phone Determination, on page 29.
If the phone is already in the Cisco Unified Communications Manager database, its configuration file may be
damaged. See the Create New Configuration File, on page 88 for assistance.
Troubleshooting and Maintenance
For more information on licensing, see the “Licenses for Phones” section in the Cisco Unified Communications
Manager System Guide.
Cisco Unified IP Phone Cannot Obtain IP Address
Problem
If a phone cannot obtain an IP address when it starts up, the phone may not be on the same network or VLAN
as the DHCP server, or the switch port to which the phone connects may be disabled.
Solution
Ensure that the network or VLAN to which the phone connects has access to the DHCP server, and ensure
that the switch port is enabled.
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 Cisco Unified Communications Manager connection are stable, a
Cisco Unified IP Phone should not reset on its own.
Typically, a phone resets if it has problems connecting to the Ethernet network or to Cisco Unified
Communications Manager.
Physical Connection Problems
Problem
The physical connection to the LAN may be broken.
Solution
Verify that the Ethernet connection to which the Cisco Unified IP Phone connects is up. For example, check
whether the particular port or switch to which the phone connects is down and that the switch is not rebooting.
Also ensure that no cable breaks exist.
Cisco Unified IP Phone Resets Unexpectedly
Intermittent network outages
Problem
Your network may be experiencing intermittent outages.
Solution
Intermittent network outages affect data and voice traffic differently. Your network might be 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 to the network. Contact the system
administrator for information on known problems in the voice network.
DHCP Settings Errors
Problem
The DHCP settings may be incorrect.
Solution
Verify that you have properly configured the phone to use DHCP. See Configuration Menus, on page 35 for
more information. Verify that the DHCP server is set up properly. Verify the DHCP lease duration. Cisco
recommends that you set it to 8 days.
The static IP address assigned to the phone may be incorrect.
Solution
If the phone is assigned a static IP address, verify that you have entered the correct settings. See Configuration
Menus, on page 35 for more information.
Voice VLAN Setup Errors
Problem
If the Cisco Unified IP Phone appears to reset during heavy network usage (for example, following extensive
web surfing on a computer connected to the same switch as the phone), it is likely that you do not have a voice
VLAN configured.
Troubleshooting and Maintenance
Solution
Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic. See the Cisco
Unified SIP Phone 3905 and VLAN Interaction, on page 22 for details.
Phones Have Not Been Intentionally Reset
Problem
If you are not the only administrator with access to Cisco Unified Communications Manager, you should
verify that no one else has intentionally reset the phones.
Solution
You can check whether a Cisco Unified IP Phone received a command from Cisco Unified Communications
Manager to reset by pressing Applications on the phone and choosing Admin Settings > Status > NetworkStatistics. If the phone was recently reset, one of these messages appears:
If the Restart Cause field displays Reset-Reset, the phone closed due to receiving a Reset/Reset from
If the phone continues to reset, eliminate DNS or other connectivity errors with Determine DNS or Connectivity
Issues, on page 89
Power Connection Problems
Problem
The phone does not appear to be powered up.
Solution
In most cases, a phone restarts if it powers up by using external power but loses that connection and switches
to PoE. Similarly, a phone may restart if it powers up by using PoE and then connects to an external power
supply.
Audio Problems
Audio Problems
The following sections describe how to resolve audio problems.
No Speech Path
Problem
One or more people on a call do not hear any audio.
Solution
When at least one person in a call does not receive audio, IP connectivity between phones is not established.
Check the configuration of routers and switches to ensure that IP connectivity is properly configured.
Choppy Speech
Problem
A user complains of choppy speech on a call.
Cause
There may be a mismatch in the jitter configuration.
Solution
Check the AvgJtr and the MaxJtr statistics. A large variance between these statistics might indicate a problem
with jitter on the network or periodic high rates of network activity.
Poor Audio Quality with Calls That Route Outside Cisco Unified Communications Manager
Problem
Poor quality occurs with tandem audio encoding. Tandem encoding can occur when calls are made between
an IP Phone and a digital cellular phone, when a conference bridge is used, or in situations where IP-to-IP
calls are partially routed across the PSTN.
Cause
In these cases, use of voice codecs such as G.729 and iLBC may result in poor voice quality.
Solution
Use the G.729 and iLBC codecs only when absolutely necessary.
General Telephone Call Problems
The following sections help troubleshoot general telephone call problem.
Phone Call Cannot Be Established
Problem
A user complains about not being able to make a call.
Cause
The phone does not have a DHCP IP address, is unable to register to Cisco Unified Communications Manager.
Phones with an LCD display show the message Configuring IP or Registering. Phones without an
LCD display play the reorder tone (instead of dial tone) in the handset when the user attempts to make a call.
Solution
1
Verify the following:
a
The Ethernet cable is attached.
b
The Cisco CallManager service is running on the Cisco Unified Communications Manager server.
c
Both phones are registered to the same Cisco Unified Communications Manager.
2
Audio server debug and capture logs are enabled for both phones. If needed, enable Java debug.
Phone Does Not Recognize DTMF Digits or Digits Are Delayed
Problem
The user complains that numbers are missed or delayed when the keypad is used.
