What Networking Protocols are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice communication. Cisco Unified IP Phone 6901 and 6911 support.

Ta b l e 1-3 Supported Networking Protocols on the Cisco Unified IP Phone

Networking Protocol Purpose Usage Notes

Cisco Audio Session Tunneling (CAST)

(Cisco Unified IP Phone 6911 only)

Cisco Discovery Protocol (CDP)

Dynamic Host Configuration Protocol (DHCP)

Hypertext Transfer Protocol (HTTP)

The CAST protocol allows IP phones and associated applications behind the phone to discover and communicate with the remote endpoints without requiring changes to the traditional signaling components like Cisco Unified Communications Manager and g ateways. The CAST protocol allows separate hardware devices to synchronize related media and it allows PC applications to augment non Video capable phones to become video enabled by using the PC as the video resource.

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.

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.

HTTP is the standard way of transferring information and moving documents across the Internet and the web.

Table 1-3 provides an overview of the networking protocols that the

—

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 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.

Cisco Unified IP Phones use HTTP for troubleshooting purposes.

What Networking Protocols are Used?

Table 1-3 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

IEEE 802.1X 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.

Internet Protocol (IP) IP is a messaging protocol that addresses

and sends packets across the network.

Link Layer Discovery Protocol (LLDP)

(Cisco Unified IP Phone

LLDP is a standardized network discovery protocol (similar to CDP) that is supported

on some Cisco and third-party devices. 6911 only) Link Layer Discovery

Protocol-Media Endpoint

LLDP-MED is an extension of the LLDP

standard developed for voice products. Devices (LLDP-MED)

The Cisco Unified IP Phone implements the IEEE

802.1X standard by providing suppo rt for the following authentication methods: EAP-FAST and EAP-TLS.

When 802.1X authentication is enabled on the phone, you should disable the voice VLAN. Refer to the

“Supporting 802.1X Authentication on Cisco Unified IP Phones” section on page 1-17 for

additional information.

To communicate using IP, network devices must have an assigned IP address, subnet, and gatewa y.

IP addresses, subnets, and gateways identificati ons 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.

The Cisco Unified IP Phone supports LLDP on the switch and PC port.

The Cisco Unified IP Phone supports LLDP-MED on th e S W p o r t t o communicate information such as:

• Voice VLAN configuration

• Device discovery

Real-Time Transport Protocol (RTP)

Real-Time Control Protocol (RTCP)

Cisco Unified IP Phone 6901 and 6911 Administration Guide for Cisco Unified Communications Manager 8.5 (SCCP and SIP)

OL-23874-01

RTP is a standard protocol for transporting real-time data, such as interactive voice and video, over data networks.

RTCP works in conjunction with RTP to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

• Power management

• Inventory management

For more information about LLDP-MED support, see the LLDP-MED and Cisco Discovery Protocol white paper:

http://www.cisco.com/en/US/technologies/tk652/tk 701/technologies_white_paper0900aecd804cd46d. html

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 Cis co

What Networking Protocols are Used?

Table 1-3 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

Session Initiation Protocol (SIP)

Skinny Client Control Protocol (SCCP)

Transmission Control Protocol (TCP)

Transport Layer Security (TLS)

Trivial File Transfer Protocol (TFTP)

SIP is the Internet Engineering T ask 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.

SCCP includes a messaging set that allows communications between call control servers and endpoint clients such as IP Phones. SCCP is proprietary to Cisco Systems.

TCP is a connection-oriented transport protocol.

TLS is a standard protocol for securing and authenticating communications.

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.

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.

Y ou can configure the Ci sco Unified IP Phone to use either SIP or Skinny Client Control Protocol (SCCP).

Cisco Unified IP Phone 6901 and 6911 use SCCP, version 20 for call control.

Cisco Unified IP Phones use TCP to connect to Cisco Unified Communicati ons Mana ger.

When security is implemented, Cisco Unified

IP Phones use the TLS protocol when securely registering with Cisco Unified

Communications Manager. For more information, refer to the Cisco Unified

Communications Manager Security Guide.

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.

Identifying Authenticated, Encrypted, and Protected Phone Calls

In an authenticated call, all devices participat ing in the establishment of the call are trusted devices, and authenticated by Cisco

In an encrypted call, all devices participating in the establishment of the call are trusted devices, and authenticated by Cisco are encrypted. An encrypted call offers a high level of security, providing integrity and privacy to the call.

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.

In a protected call, a security tone plays at the beginning of a call to indicate that the other connected phone is also receiving and transmitting encrypted audio and video (if video is involved). If your call is connected to a non-protected phone, the security tone does not play.

Establishing and Identifying Protected Calls

A protected call is established when your phone, and the phone on the other end, is configured for protected calling. The other phone can be in the same Cisco IP network, or on a network outside the IP network. Protected calls can only be made between two phones. Conference calls and other mult iple-line calls are not supported.

A protected call is established using this process:

1. A user initiates the ca ll from a protected phone (protected security mode).

2. A security tone plays if the call is connected to another protected phone, indicating that both ends

of the conversation are encrypted and protected. If the call is connected to a non-protected phone, then the secure tone is not played.

Note Protected calling is supported for conversations between two phones. Some features, such as conference

calling and shared lines are not available when protected calling is configured.

Call Security Interactions and Restrictions

Cisco Unified Communication s Manage r checks the phone security status when conferences are established and changes the security indication for the conference or blocks the completion of the call to maintain integrity and also security in the system.

Supporting 802.1X Authentication on Cisco Unified IP Phones

These sections provide information about 802.1X support on the Cisco Unified IP Phones:

• Overview, page 1-17

• Required Network Components, pa ge 1-18

• Best Practices—Requirements and Recommendations, page 1-19

Overview

Cisco Unified IP phones and Cisco Catalyst switches have traditionally used Cisco Discovery Protocol (CDP) to identify each other and determine parameters such as VLAN allocation and inline power requirements. However, CDP is not used to identify any locally attached PCs; therefore, Cisco Unified IP Phones provide an EAPOL pass-through mechanism, whereby a PC locally attached to the IP phone, may pass through EAPOL messages to the 8 02.1X auth enticator in the LAN switch. This prevents the IP phone from having to act as the authent icator, yet allows the LAN switch to authenticate a data end point prior to accessing the network.

In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP Phones provide a proxy EAPOL-Logoff mechanism. In the event that the locally attached PC is disconnected from the IP phone, the LAN switch would not see the physical link fail, because the link between the LAN switch and the IP phone is maintained. T o avoid compromising network in tegrity , the IP phone sends an EAPOL-Logof f message to the switch, on behalf of the downstream PC, which triggers the LAN switch to clear the authentication entry for the downstream PC.

OL-23874-01

The Cisco Unified IP phones also contain an 802.1X supplicant , in additio n to the EA POL pass-through mechanism. 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 and EAP-TLS options for network authentication.

Understanding Security Features for Cisco Unified IP Phones

Required Network Components

Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:

• Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which initiates the request to

access the network.

• Cisco Secure Access Control Server (ACS) (or other third-party authentication server)—The

authentication server and the phone must both be configured with a shared secret that is used to authenticate the phone.

• Cisco Catalyst Switch (or other third-party switch)—The switch must support 802.1X, so it can act

as the authenticator and pass the messages between the phone and the authentication server. When the exchange is completed, the switch then grants or denies the phone access to the network.

OL-23874-01

Chapter 1 An Overview of the 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 th e other components before enab ling 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.

Note Only Cisco Unified IP Phone 6911 has PC ports.

–

Enabled—If you are using a switch that supports multi-domain authentication, you can enable the PC port and connect a PC to it. In this case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor the authentication exchanges between the switch and the attached PC. For more information about IEEE 802.1X support on the Cisco Catalyst switches, refer to the Cisco Catalyst switch configuration guides at:

http://www.cisco.com/en/US/products/hw/switches/ps708/tsd_products_support_series_home. html

–

Disabled—If the switch does not suppor t multi ple 802 .1X- compli ant 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.

Overview of Configuring and Installing Cisco Unified IP Phones

–

Enabled—If you are using a switch that supports multi-domain authenticatio n, you can continue to use the voice VLAN.

–

Disabled—If the switch does not support multi-domain authentication, di sable the Voice VLAN and consider assigning the port to the native VLAN.

Understanding How the Cisco Unified IP Phone 6911 Interacts with the VLAN

The Cisco Unified IP Phone 6911 has an internal Et hernet swit ch, enabling forwarding o f packets to the phone, and to the access port and the network port on the back of the phone.

Note Cisco Unified IP Phone 6901 does not support PC port.

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:

2-2

• 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.

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

• 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 traf fic.

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)

Understanding Phone Configuration Files

Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager that requires the phone to be reset, a change is automatically made to the phone’s configuration file.

Configuration files also contain information about which i mage 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.

In addition, if the device security mode in the configuration file is set to Auth enticated and the CTL file on the phone has a valid certificate for Cisco a TLS connection to Cisco connection.

Note If the device security mode in the configuration file is set to Authenticated or Encrypted, but the phone

has not received a CTL file, the phone tries four times to obtain a CTL file so it can register securely.

phone requests a configuration file whenever it resets an d 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:

Understanding the Phone Startup Process

• 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.

If the phone is registered and working in encrypted mode, the phone accesses the configuration file named SEPmac_address.cnf.xml.enc.sgn. If the SEPmac_address.cnf.xml.enc.sgn does not exist on the TFTP server, the phone requests for the file SEPmac_address.cnf.xml.sgn. That is, if phone works in encrypted mode with TFTP Encrypted Config selected, the phone accesses the config uration file named SEPMac_addr.cnf.xml.enc.sgn if it is not chosen, SEPMac_addr.cnf.xml.sgn is chosen. T o enable TFTP Encrypted Configuration, select th e TFTP Encrypted Config check box Phone Security Profile Configuration page. You can access this page from the Cisco Unified CM Administration UI by selecting System > Security> Phone Security Profile and then clicking Add New.

For SIP phones, the TFTP server generates these SIP configuration files:

• SIP IP Phone:

–

For unsigned and unencrypted files—SEP<mac>.cnf.xml

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

–

For signed files—SEP<mac>.cnf.xml.sgn

–

For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn

• Dial Plan—<dialplan>.xml

The filenames are derived from the MAC address and description fiel ds in the Phon e Config uration window of Cisco

Unified Communications Manager Administration. The MAC address uniquely

identifies the phone. For more information on phone configuration settings, go to the Cisco Unified IP Phone Configuration

chapter in the Cisco Communications Manager Administration Guide.

Understanding the Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone 6901 and 6911 go through a standard startup process that is described in of these steps may occur on your Cisco Unified IP Phone.

Ta b l e 2-3 Cisco Unified IP Phone Startup Process

Task Purpose Related Topics

1. Obtaining 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.

2. Configuring 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.

Task Purpose Related Topics

3. Obtaining 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 us ing DHCP in your network, you must assign static IP addresses to each phone locally.

4. Accessing 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 You can also assign an alternative TFTP server to use instead of the

one assigned by DHCP.

5. Requesting the Configuration File

The TFTP server has configuration files, which define parameters for connecting to Cisco Unified information for the phone.

6. Loading the Stored Phone Image

The Cisco Unified 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.

7. Contacting Cisco Unified Communications Manager

The configuration file defines how the Cisco Unified IP Phone communicates with Cisco Unified 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

Automatic Port Synchronization

(Cisco Unified IP Phone 6911 only)

When the Cisco Unified CM administrator uses the Remote Port Configuration feature to set the speed and duplex function of an IP phone remotely, loss of packets can occur if one port is slower than the other.

To configure the parameter in the Cisco Unified CM Administration application, choose Device > Phone, select the appropriate IP phones, and scroll to the Product Specific Configuration Layout

pane.

The Automatic Port Synchronization feature synchronizes the ports to the lowest s peed amon g the two ports, which eliminates packet loss. When automatic port synchronization is enabled, it is recommended that both ports be configured for autonegotiate. If one port is enable d for autonegotiate and the other is at a fixed speed, the phone synchronizes to the fixed port speed.

Note If both the ports are configured for fixed

speed, the Automatic Port Synchronization feature is ineffective. The Remote Port Configuration and Automatic Port Synchronization features are compatible only with IEEE 802.3AF Power of Ethernet (PoE) switches. Switches that support only Cisco Inline Power are not compatible. Enabling this feature on phones that are connected to these types of switches could result in loss of connectivity to Cisco Unified CM, if the phone is powered by PoE.

Auto Barge Allows user to cbarge into a shared line call

automatically.

Block External to External Transfer

Prevents users from transfer ring an external c all to another external number.

Call Forward Allows users to redirect incoming calls to another

number . Call forward options include Call Forward All, Call Forward Busy, Call Forward No Answer , and Call Forward No Coverage.

You will hear a stutter tone after off-hook if Call Forward All feature is configured on your phon e.

To configure the setting on multiple phones simultaneously, enable Automatic Port Synchronization in either the Enterprise Phone Configuration (System > Enterprise Phone Configuration) or the Common Phone Profile Configuration (Device > Device Settings > Common Phone Profile).

Resolving Startup Problems

Symptom: The Cisco Unified IP Phone Does Not Go Through its Normal Startup Process

When you connect a Cisco Unified IP Phone into the network port, the phone should go through its normal startup process as described in 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.

T o determine whether the phone is functional, follow these suggestions to systematicall y eliminate these other potential problems:

1. Verify that the network port is functional:

–

Exchange the Ethernet cables with cables that you know are functional.

–

Disconnect a functioning Cisco Unified IP Phone from another port and connect it to this network port to verify the port is active.

–

Connect the Cisco Unified IP Phone that will not start up to a different network port that is known to be good.

–

Connect the Cisco Unified IP Phone that will not start up directly to the port on the switch, eliminating the patch panel connection in the office.

2. Verify that the phone is receiving power:

–

If you are using external power, verify that the electrical outlet is functional.

–

If you are using in-line power, use the external power supply instead.

–

If you are using the external power supply, switch with a unit that you know to be functional.

3. If the phone still does not start up properly, perform a factory reset of the phone. For instructions,

see the

If after attempting these solutions, the phone still does not function, contact a Cisco technical support representative for additional assistance.

In addition, problems with security may prevent the phone from starting up properly. See the “General

Troubleshooting Tips” section on page 7-8 for more information.

Identifying Error Messages

As the phone cycles through the startup pr ocess, you can access st atus messages th at mi ght pr ovi de you with information about the cause of a problem. See the instructions about accessing status messages.

Checking Network Connectivity

If the network is down between the phone and the TFTP server or Cisco Unified Communications Manager, the phone cannot start up properly. Ensure that the network is currently running.

Verifying TFTP Server Settings

You ca n determine the IP address of the TFTP server used by the phone by pressing the *, #, and 0 buttons simultaneously, entering the password, and then following the voice prompts to review the network setting.

If you have assigned a static IP address to the phone, you must manually enter a setting for the TFTP Server 1 option. See the

Resolving Startup Problems

“Device Logs” section on page 6-9 for

“Configuring Settings on the Cisco Unified IP Phone” section on page 4-1.

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 or Option 66.

You can also enable the phone to use an alternate TFTP server. Such a setting is particularly useful if t he phone was recently moved from one location to another. See the

Unified IP Phone” se ction on pa ge 4-1 for instructions.

Verifying IP Addressing and Routing

Y ou should verify the IP addressing and routing sett ings on the phone. If y ou are using DHCP, the DHCP server should provide these values. If you have assigned a static IP address to th e phone, you must enter these values manually.

On the Cisco Unified IP Phone, press the *, #, and 0 buttons simultaneously, enter the password, and then follow the voice prompts to review the following options:

• IP Address, Subnet Mask, Default Router—If you have assigned a static IP address to the phone,

you must manually enter settings for these options. See the

Unified IP Phone” se ction on pa ge 4-1 for instructions.

If you are using DHCP, check the IP addresses distributed by your DHCP server. Refer to the Understanding and Troubleshooting DHCP in Catalyst Switch or Enterprise Networks document, available at this URL:

Resolving Startup Problems

Cisco CallManager and TFTP Services Are Not Running

If the Cisco CallManager or TFTP services are not running, phones may not be able to start up properly. However, in such a situation, it is likely that you are experiencing a system-wide failure, and other phones and devices are unable 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.

To start a service, follow these steps:

Procedure

Step 1 From Cisco Unified Communications Manager Administration, choose Cisco Unified Serviceability

from the Navigation drop-down list and click Go.

Step 2 Choose Tools > Control Center - Feature Services. Step 3 Choose the primary Cisco Unified Communications Mana ger serve r from the Server drop-down list.

The window displays the service names for the server that you chose, the status of the services, and a service control panel to start or stop a serv ice.

Cisco Unified IP Phone Resets Unexpectedly

If users report that their phones are resetting during calls or while idle on their desk, you should investigate the cause. If the network connection and Cisco connection are stable, a Cisco

Typically, a phone resets if it has problems connecting to the Ethernet network or to Cisco Unified Communications Manager. These sections can help you identify the cause of a phone resetting in your network:

• Verifying the Physical Connection, page 7-6

• Identifying Intermittent Network Outages, page 7-6

• Verifying DHCP Settings, page 7-6

• Checking Static IP Address Settings, page 7-7

• Verifying that the Phones Have Not Been Intentionally Reset, page 7-7

• Eliminating DNS or Other Connectivity Errors, pa ge 7-7

Unified IP Phone should not reset on its own.

Unified Communications Manager

Verifying the Physical Connection

V erify that the Ethernet connection to which the Cisco Unified IP Phone is connected is up. For example, check whether the particular port or switch to which the phone is connected is down and t hat the swi tch is not rebooting. Also make sure that there are no cable breaks.

Identifying Intermittent Network Outages

Intermittent network outages affect data and voice traffic differently. Your network might have been experiencing intermittent outages without detection. If so, data traffic can rese nd lost packets and verify that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather than retransmitting a lost ne twork connecti on, the phone resets and attempts to reconnect its network connection.

If you are experiencing problems with the voice network, you should investigate whether an existing problem is simply being exposed.

Verifying DHCP Settings

The following suggestions can help you determine if the phone has been properly configured to use DHCP:

1. Verify that you have properly configured the phone to use DHCP. See the “Configuring Settings on

the Cisco Unified IP Phone” section on page 4-1 for more information.

7-6

2. Verify that the DHCP server has been set up properly.

3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.

Chapter 7 Troubleshooting and Maintenance

Cisco Unified IP Phone Resets Unexpectedly

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 Settings on the Cisco Unified IP Phone” section on page 4-1 for more information.

Verifying the Voice VLAN Configuration

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 li kely that you do not have a voice VLAN configured.

Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic. See the

“Understanding How the Cisco Unified IP Phone 6911 Interacts with the VLAN” section on page 2-2

for details.

Verifying that the Phones Have Not Been Intentionally Reset

If you are not the only administrator with access to Cisco Unified Communications Manager, you should verify that no one else has intentio nally reset the phones.

You can check whether a Cisco Unified IP Phone received a command from Cisco Unified Communications Manager to reset by pressing the Applications button on the phone and choosing Administrator Settings > Status > Network Statistics. If the phone was recently reset, one of these messages appears:

• Reset-Reset—Phone closed due to receiving a Reset/Reset from Cisco Unified Communications

Manager Administration.

• Reset-Restart—Phone closed due to receiving a Reset/Restart from Cisco Unified Communications

Manager Administration.

Eliminating DNS or Other Connectivity Errors

If the phone continues to reset, follow these steps to eliminate DNS or other connectivity errors:

Procedure

Step 1 Use the Reset Settings menu to reset phone settings to their default values. See the “Resetting or

Restoring the Cisco Unified IP Phone” section on page 7-10 for details.

Step 2 Modify DHCP and IP settings:

a. Disable DHCP. See the “Configuring Settings on the Cisco Unified IP Phone” section on page 4-1

for instructions.

b. Assign static IP values to the phone. See the “Configuring Settings on the Cisco Unif ied IP Phone”

section on page 4-1 for instructions. Use the same default router setting used for other functioning

Cisco Unified IP Phones.

OL-23874-01

c. Assign a TFTP server. See the “Configuring Settings on the Cisco Unified IP Phone” section on

page 4-1 for instructions. Use the same TFTP server used for other functioning Cisco Unified IP

Phones.

Ta b l e 7-1 Cisco Unified IP Phone Troubleshooting

Summary Explanation

Connecting a Cisco Unified IP Phone to another Cisco Unified IP Phone.

Poor quality when calling digital cell phones using the G.729 protocol.

Prolonged broadcast storms cause IP

phones to reset, or be unable to

make or answer a call. Moving a network connection from the

phone to a workstation.

Cisco does not support connecting an IP phone to another IP phone through the PC port. Each IP phone should directly connect to a switch port. If phones are connected together in a line (by using the PC port), the phones will not work.

In Cisco Unified Communications Manager, you can configure the network to use the G.729 protocol (the default is G.711). When using G.729, calls between an IP phone and a digital cellular phone will have poor voice quality. Use G.729 only when absolutely necessary.

A prolonged Layer 2 broadcast storm (lasting several minutes) on th e v oice VLAN may cause IP phones to reset, lose an active call, or be unable to initiate or ans wer a call. Phones may not come up until a broadcast storm ends.

If you are powering your phone through the network connection, you must be careful if you decide to unplug the phone’s network connection and plug the cable into a desktop computer.

Caution The computer’s network card cannot receive power through the network

connection; if power comes through the connection, the network card can be destroyed. To protect a network card, wait 10 seconds or longer after unplugging the cable from the phone before plugging it into a computer. This delay gives the switch enough time to recognize that there is no longer a phone on the line and to stop providing power to the cable.

Summary Explanation

Changing the telephone configuration. By default, the network configuration options are locked to prevent users from

making changes that could impact their network connectivity. You must unlock the network configuration options before you can configure them. See the

the Phone Configuration Settings” section on page 4-2 for details.

Phone resetting. The phone resets when it loses contact with the Cisco Unified Communications

Manager software. This lost connection can be due to any network connectivity disruption, including cable breaks, switch outages, and switch reboots.

Dual-Tone Multi-Frequency (DTMF) delay.

Codec mismatch between the phone and another device.

When you are on a call that requires keypad input, if you press the keys too quickly, some of them might not be recogn ized.

The RxType and the TxType statistics show the codec that is being used for a conversation between this Cisco Unified

IP phone and the other device. The values of these statistics should match. If they do not, verify that the other device can handle the codec conversation, or that a transcoder is in place to handle the service.

Sound sample mismatch between the phone and another device.

The RxSize and the TxSize statistics show the size of the voice packets that are being used in a conversation between this Cisco Unified

IP phone and the other

device. The values of these statistics should match.

Gaps in voice calls. 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.

Loopback condition. A loopback condition can occur when the following conditions are met:

“Accessing

• The SW Port Configuration option in the Network Configuration menu on the

phone is set to 10 Half (10-BaseT / half duplex)

• The phone receives power from an exte rnal power su pply

• The phone is powered down (the power supply is disconnected)

In this case, the switch port on the phone can become disabled and the following message will appear in the switch console log:

HALF_DUX_COLLISION_EXCEED_THRESHOLD To resolve this problem, re-enable the port from the switch.

One-way audio. When at least one person in a call does not receive audio, IP connectivity between

phones is not established. Check the configurations in routers and switches to ensure that IP

connectivity is properly configured.

Phone call cannot be established. Th e phone does not have a DHCP IP address, is unable to register to Cisco Unified

Communications Manager, and shows a Configuring IP or Registering message. Verify the following:

1. The Ethernet cable is attached.

2. The Cisco CallManager service is running on the Cisco Unified

Communications Manager server.

3. Both phones are registered to the same Cisco Unified Communications

Manager.

4. Audio server debug and capture logs are enabled for both phones. If needed,

enable Java debug.
