Related Commands

To change the security mode of the Cisco Unified CME phone authentication server, use the server-security-mode command in telephony-service configuration mode. To change the mode from secure to nonsecure, use the no form of this command.

Syntax Description

Command Default

When the CTL file is initially generated, the mode is set to secure.

Command Modes

Telephony-service configuration (config-telephony)

Command History

Usage Guidelines

This command is used with Cisco Unified CME phone authentication.

This command has no effect until the CTL file is initially generated by the CTL client. When the CTL file is successfully generated, the CTL client automatically sets the server security mode to secure. You can then toggle the mode from secure to nonsecure using this command.

After toggling between secure and non-secure mode, you must use the regenerate command in CTL-client configuration mode to generate the CTL file. This is necessary because if the security mode is nonsecure, its credentials are zeroed out in the CTL file. If the security mode is secure, the CTL file contains the server’s credentials.

The no version of this command sets the mode to non-secure; it does not remove the command from your configuration.

To remove this command from your configuration and revert to the state before the Cisco Unified CME security feature was activated, use the erase keyword and follow the instructions displayed on the console. When you use this command with the erase keyword, the router checks whether the Cisco IOS CTL-provider process is running, and if not, it deletes the CTL file from router storage. After using this command to delete the CTL file, you must manually delete the CTL file from any SCCP phones that had downloaded it previously.

Related Commands

To allow the display of names associated with called numbers for incoming calls on IP phones, use the service dnis dir-lookup command in telephony-service configuration mode. To deactivate directory lookup, use the no form of this command.

Command Default

The default is directory service lookup is inactive.

Command Modes

Telephony-service configuration (config-telephony)

Command History

Usage Guidelines

The service dnis dir-lookup command provides a called number to the name-lookup service to support display of the name associated with the called number for incoming calls to IP phones. The display name is obtained from the Cisco CME system’s list of Cisco CME directory names created using the directory entry command in the telephony-service configuration mode.

Called numbers can be displayed for overlaid ephone-dn and for ephone-dns that are not overlaid. Secondary line are supported.

To allow a single ephone-dn to receive calls for multiple different called numbers (with different names), you must use wildcard “.” characters in the number field for the ephone-dn.

To use the service dnis dir-lookup command in conjunction with the ephone-hunt, you can configure the ephone-hunt group to use a pilot number that contains wildcard “.” characters. This command allows the ephone-hunt group to receive calls from different numbers. Individual ephone-dns that are configured as members of the hunt group with the ephone-hunt list must not have wildcard characters in their number fields.

If the service dnis dir-lookup is used at the same time as the service dnis overlay, the directory-lookup service takes precedence in resolving the name for the called number.

Related Commands

To allow incoming calls to an ephone-dn overlay to display called ephone-dn names, use the service dnis overlay command in telephony-service configuration mode. To deactivate the service dialed number identification service (DNIS) overlay, use the no form of this command.

Command Default

The ephone-dn names in an ephone-dn overlay are not displayed on IP phones.

Command Modes

Telephony-service configuration (config-telephony)

Command History

Usage Guidelines

The service dnis overlay allows phone users to determine which ephone-dn within an overlay set is being called. Up to ten ephone-dns are allowed per overlay set. When an incoming call is presented under a service dnis overlay configuration, the phone displays the name of the individual ephone-dn according to the name configured under the ephone-dn configuration mode. Note that for an ephone-dn name to be displayed on IP phones, you must first assign ephone-dn names with the name command in ephone-dn configuration mode.

The number of the first ephone-dn listed in the button is the default display for all phones using the same set of overlaid ephone-dns. Calls to the first ephone-dn display the caller ID. Calls to the remaining ephone-dns display ephone-dn names. For example, if there are three phones with one overlay set containing five ephone-dns, the first ephone-dn’s number listed is the default display for all three phones. A call to the first ephone-dn displays the caller ID on all phones until the call is picked up. When the call is answered by phone 1, the displays in phone 2 and phone 3 return to the default display. Calls to the last four ephone-dns display ephone-dn names.

If the service dnis overlay is used at the same time as the service dnis dir-lookup, the service dnis dir-lookup takes precedence in determining the name to be displayed.

Related Commands

To modify the vendorConfig parameters in the configuration file, use the service phone command in telephony-service or ephone-template configuration mode. To disable a setting, use the no form of this command.

Syntax Description

Command Default

The vendorConfig parameters in phone configuration files are set to default values.

Command Modes

Telephony-service configuration (config-telephony)
Ephone-template configuration (config-ephone-template)

Command History

Usage Guidelines

This command in telephony-service configuration mode modifies vendorConfig parameters in configuration file for phones in a Cisco Unified CME system.

The vendorConfig section of a configuration file is read by a phone’s firmware when that Cisco Unified IP phone is booted. The number and type of parameters may vary from one firmware version to the next.

If a firmware version does not support a particular parameter, that parameter cannot be implemented. For example, Cisco phone firmware 8.2.1 or a later version is required to support the G.722-64K codec on G.722-capable SCCP phones and Cisco phone firmware 8.3.1 or a later version is required to support the G.722-64K codec on G.722-capable SIP phones. If your phones are loaded with an earlier version of phone firmware, they cannot support the G.722-64K codec regardless of how the g722CodecSupport parameter is configured.

The IP phone that downloads the configuration file will implement only those parameters that it can support and ignore configured parameters that it cannot implement. For example, a Cisco IP phone without a backlit display cannot implement backlight parameters regardless of how they are configured.

In Cisco Unified CME 4.0 and later versions, support for creating configuration files at a phone level was added for SCCP phones. This command in ephone-template configuration mode creates an template of vendorConfig parameters that can be applied to individual SCCP phones in Cisco Unified CME. This command in ephone-template configuration mode does not work for all vendorConfig parameters. See the table below for information about individual parameters.

In Cisco Unified CME 4.0 and later versions, if you use an ephone template to apply this command to one or more phones, you must also configure the cnf-file perphone command so that a separate configuration file is created for each phone, by MAC address. To apply this command in telephony-service mode to all phones of a particular type in Cisco Unified CME 4.0 and later versions, you can configure the cnf-file perphonetype command to specify that configuration files are generated by phone type.

To apply this command in telephony-service configuration mode to all phones in your Cisco Unified CME system, ensure that the system is configured for the default single per-system configuration file for all phones.

If you use an ephone template to apply this command to a phone and you also use this command in telephony-service configuration mode for the same phone, the value that you set in ephone-template configuration mode has priority.

After modifying the vendorConfig parameters, you must generate new configuration files.

After generating configuration files, reset or reboot the IP phone to be configured to download the new configuration file.

Use the show telephony-service tftp-binding command to view the SEP*.cnf.xml files that are associated with individual phones. The following example entry from a Sep*.conf.xml file disables the PC port on a phone:

<vendorConfig>
<pcPort>1</pcPort>
</vendorConfig>

The below table lists the basic vendorConfig parameters in alphabetical order.

Note	Parameter names are word and case-sensitive and must be typed exactly as shown.

Router(config)# telephony-service
Router(config telephony-service)# service phone
 specialNumbers 411,511,911

A session manager in Cisco Unified CME can manage and monitor Register and Subscribe messages.

Before configuring this command, a session manager must already configured in Cisco Unified CME by using the voice register session-server command.

Use the session-server command in voice register pool configuration mode to specify that Register and Subscribe messages for an external feature-server route point must contain a Cisco-referenceID field. Registration or subscription will be granted only for the specified route point. The route point for which Register and Subscribe messages are to be managed by this session manager must already be configured as a SIP endpoint in Cisco Unified CME. Typically, the configuration for the route point is provided from the feature server. If the configuration for the route point is deleted or must be modified, it can be reconfigured directly in Cisco Unified CME by using Cisco IOS commands. Each route point can be managed by only one session manager. Each session manager can manage multiple route points.

Use the session-server command in ephone-dn configuration mode or in voice register dn configuration mode to specify that Subscribe messages for a directory number must contain a Cisco-referenceID field. Registration or subscription will be granted only for the specified directory number. The directory number for which Subscribe messages are to be monitored by this session manager must already be configured in Cisco Unified CME. Each directory number can be monitored by up to eight session managers. Each session manager can subscribe for multiple directory numbers.

To specify the transport layer protocol that a SIP phone uses to connect to Cisco Unified CME, use the session-transport command in voice register pool or voice register template configuration mode. To reset to the default value, use the no form of this command.

Syntax Description

Command Default

UDP is the default protocol.

Command Modes

Voice register pool configuration (config-register-pool)
Voice register template configuration (config-register-temp)

Command History

Usage Guidelines

This command sets the transport layer protocol parameter in the phone’s configuration file.

If you use a voice register template to apply a to a phone and you also use the same command in voice register pool configuration mode for the same phone, the value that you set in voice register pool configuration mode has priority.

This command is not supported on the Cisco Unified IP Phone 7905, 7912, 7940, or 7960.

Note

Although this command is not supported for the Cisco Unified IP Phone 7905, 7912, 7940, or 7960, it can be used to assign TCP as the session transport type for these phones. If TCP is selected for an unsupported phone using this command, calls to that phone will not complete successfully. The phone can originate calls but it uses UDP, although TCP has been assigned.
