Cisco IOS Voice Commands:
C

---

This chapter contains commands to configure and maintain Cisco IOS voice applications. The commands are presented in alphabetical order. Some commands required for configuring voice may be found in other Cisco IOS command references. Use the command reference master index or search online to find these commands.

For detailed information on how to configure these applications and features, refer to the Cisco IOS Voice Configuration Library.

cac master

To configure the call admission control (CAC) operation as master, enter the cac master command in voice-service configuration mode. To restore CAC operation to slave, use the no form of this command.

cac master

no cac master

Syntax Description

This command has no arguments or keywords.

Defaults

CAC operation is slave

Command Modes

Voice-service configuration

Command History

Release	Modification
12.1(1)XA	This command was introduced on the Cisco MC3810.
12.1(2)T	This command was integrated into Cisco IOS Release 12.1(2)T.
12.2(2)T	This command was implemented on the Cisco 7200 series.

Usage Guidelines

You should configure the router at opposite ends of an ATM adaptation layer 2 (AAL2) trunk for the opposite CAC operation—master at one end and slave at the other end.

A router configured as a master always performs CAC during fax and modem upspeed. A router configured as a slave sends a request for CAC to the CAC master.

Examples

The following example shows configuration of the CAC operation of a router as master:

voice service voatm

 session protocol aal2

 cac master

The following example shows configuration of these entities being returned to slave status:

voice service voatm

 session protocol aal2

 no cac master

cac_off

To disable connection admission control (CAC), use the cac_off command in interface-ATM-VC configuration mode. To enable CAC, use the no form of this command.

cac_off

no cac_off

Syntax Description

This command has no keywords or arguments.

Command Default

Call admission control is enabled.

Command Modes

Interface-ATM-VC configuration

Command History

Release	Modification
12.3(4)XD	This command was introduced.
12.3(7)T	This command was integrated into Cisco IOS Release 12.3(7)T.

Usage Guidelines

Connection admission control (CAC) is a set of actions taken by each ATM switch during connection setup to determine whether the requested quality of service (QoS) will violate the QoS guarantees for established connections. CAC reserves bandwidth for voice calls, however, the bandwidth required when the lossless compression codec (LLCC) is used is dynamic and usually less than what is generally reserved by CAC. Disabling CAC can help in better utilization of bandwidth when LLCC is used.

Examples

The following example disables call admission control on a PVC:

interface ATM0/IMA1.1 point-to-point

 pvc test1 15/135

  cac_off 

cache (neighbor BE)

To configure the local border element (BE) to cache the descriptors received from its neighbors, use the cache command in neighbor BE configuration mode. To disable caching, use the no form of this command.

cache

no cache

Syntax Description

This command has no arguments or keywords.

Defaults

Caching is not enabled

Command Modes

Neighbor BE configuration

Command History

Release	Modification
12.2(2)XA	This command was introduced.
12.2(4)T	This command was integrated into Cisco IOS Release 12.2(4)T. Support for the Cisco AS5300 universal access server, Cisco AS5350, Cisco AS5400 is not included in this release.
12.2(2)XB1	This command was implemented on the Cisco AS5850.
12.2(11)T	This command was integrated into Cisco IOS Release 12.2(11)T.

Usage Guidelines

Use this command to configure the local BE to cache the descriptors received from its neighbor. If caching is enabled, the neighbors are queried at the specified interval for their descriptors.

Examples

The following example shows the border element enabled to cache the descriptors from its neighbors.

Router(config-annexg-neigh)# id neighbor-id

Router(config-annexg-neigh)# cache

Related Commands

Command	Description
id	Configures the local ID of the neighboring BE.
port	Configures the neighbor's port number that is used for exchanging Annex G messages.
query-interval	Configures the interval at which the local BE queries the neighboring BE.

cache reload time (global application configuration mode)

To configure the router to reload scripts from cache on a regular interval, use the cache reload time command in global application configuration mode. To set the value to the default, use the no form of this command.

cache reload time bg-minutes

no cache reload time

Syntax Description

bg-minutes

Number of minutes after which the background process is awakened. This background process checks the time elapsed since the script was last used and whether the script is current: •If the script has not been used in the last "unload time," it unloads the script and quits. The unload time is not configurable. •If the script has been used, the background process loads the script from the URL. It compares the scripts, and if they do not match, it begins using the new script for new calls.

Command Default

30 minutes

Command Modes

Global application configuration

Command History

Release	Modification
12.3(14)T	The call application cache reload time command was moved to global application configuration mode and changed to cache reload time.

Command Modes

Voice-class configuration

Command History

Release	Modification
12.1(3)T	This command was introduced on the Cisco 2600 series, Cisco 3600 series, the Cisco MC3810.

Usage Guidelines

A cadence list enables the router to match a complex tone pattern from a PBX or public switched telephone network (PSTN). A tone is detected if it matches any configured cadence list. You can create up to ten cadence lists, enabling the router to detect up to ten different tone patterns. If the tone to be detected consists of only one on-off cycle, you can configure this in either of two ways:

•Create a cadence list using only the cycle-1-on-time and cycle-1-off-time variables.

•Use the cadence-max-off-time and cadence-min-on-time commands.

You must also configure the times of the cadence-max-off-time and cadence-min-on-time commands to be compatible with the on and off times specified by the cadence-list command. The time of the cadence-max-off-time must be equal to or greater than the longest off-time in the cadence list; the cadence-min-on-time must be equal to or less than the shortest on-time in the cadence list.

Examples

The following example shows configuration of cadence list 1 with three on/off cycles and cadence list 2 with two on/off cycles for voice class 100:

voice class dualtone 100

 cadence-list 1 100 100 300 300 100 200

 cadence-list 2 100 200 100 400

call-agent

To define the call agent for a Media Gateway Control Protocol (MGCP) profile, use the call-agent command in MGCP profile configuration mode. To return to the default values, use the no form of this command.

call-agent {dns-name | ip-address} [port] [service-type type] [version protocol-version]

no call-agent

Syntax Description

dns-name	Fully qualified domain name (including host portion) for the call agent. For example, "ca123.example.net".
ip-address	IP address of the call agent.
port	(Optional) User Datagram Protocol (UDP) port number over which the gateway sends messages to the call agent. Range is from 1025 to 65535. •The default call-agent UDP port is 2727 for MGCP 1.0, Network-based Call Signaling (NCS) 1.0, and Trunking Gateway Control Protocol (TGCP) 1.0. •The default call-agent UDP port is 2427 for MGCP 0.1 and Simple Gateway Control Protocol (SGCP).
service-type type	(Optional) Protocol service type valid values for the type argument are mgcp, ncs, sgcp, and tgcp. The default service type is mgcp.
version protocol-version	(Optional) Version number of the protocol. Valid values follow: •Service-type MGCP—0.1, 1.0 •Service-type NCS—1.0 •Service-type SGCP—1.1, 1.5 •Service-type TGCP—1.0 The default service type and version are mgcp and 0.1.

Command Default

The default call-agent UDP port is 2727 for MGCP 1.0, Network-based Call Signaling (NCS) 1.0, and Trunking Gateway Control Protocol (TGCP) 1.0.
The default call-agent UDP port is 2427 for MGCP 0.1 and Simple Gateway Control Protocol (SGCP).
The default service type and version are MGCP 0.1.

Command Modes

MGCP profile configuration

Command History

Release	Modification
12.2(2)XA	This command was introduced.
12.2(4)T	This command was integrated into Cisco IOS Release 12.2(4)T.
12.2(11)T	This command was implemented on the Cisco AS5300 and Cisco AS5850.

Usage Guidelines

This command is used when values for a MGCP profile are configured.

Call-agent configuration for an MGCP profile (with this command) and global call-agent configuration (with the mgcp call-agent command) are mutually exclusive; the first to be configured on an endpoint blocks configuration of the other on the same endpoint.

Identifying call agents by Domain Name System (DNS) name rather than by IP address in the call-agent command provides call-agent redundancy, because a DNS name can have more than one IP address associated with it. If a call agent is identified by a DNS name and a message from the gateway fails to reach the call agent, the max1 lookup and max2 lookup commands enable a search from the DNS lookup table for a backup call agent at a different IP address.

The port argument configures the call agent port number (the UDP port over which the gateway sends messages to the call agent). The reverse, or the gateway port number (the UDP port over which the gateway receives messages from the call agent), is configured by specifying a port number in the mgcp command.

The service type mgcp supports the Restart In Progress (RSIP) error messages sent by the gateway if the mgcp sgcp restart notify command is enabled. The service type sgcp ignores the RSIP messages.

Examples

The following example defines a call agent for the MGCP profile named "tgcp_trunk":

Router(config)# mgcp profile tgcp_trunk

Router(config-mgcp-profile)# call-agent 10.13.93.3 2500 service-type tgcp version 1.0

Related Commands

Command	Description
max1 lookup	Enables DNS lookup of the MGCP call agent address when the suspicion threshold value is reached.
max2 lookup	Enables DNS lookup of the MGCP call agent address when the disconnect threshold value is reached.
mgcp	Starts and allocates resources for the MGCP daemon.
mgcp call-agent	Configures the address of the call agent (media gateway controller).
mgcp profile	Initiates MGCP profile mode to create and configure a named MGCP profile associated with one or more endpoints or to configure the default profile.

call application alternate

---

Note Effective with Cisco IOS Release 12.3(14)T, the call application alternate command is replaced by the service command in global application configuration mode. See the service command for more information.

---

To specify an alternate application to use if the application that is configured in the dial peer fails, use the call application alternate command in global configuration mode. To return to the default behavior, use the no form of this command.

call application alternate [application-name]

no call application alternate

Syntax Description

application-name

(Optional) Name of the specific voice application to use if the application in the dial peer fails. If a specific application name is not entered, the gateway uses the DEFAULT application.

Command Default

The call is rejected if the application in the dial peer fails.

Command Modes

Global configuration

Command History

Release	Modification
12.2(11)T	This command was introduced.
12.3(14)T	This command was replaced by the service command in global application configuration mode.

Usage Guidelines

If this command is not configured, calls are rejected when the dial peer that matches the call does not specify a valid voice application.

In releases before Cisco IOS Release 12.2(11)T, the default application (DEFAULT) was automatically triggered if no application was configured in the dial peer or if the configured application failed. The default application is no longer automatically executed unless the call application alternate command is configured.

The application named DEFAULT is a simple application that outputs dial tone, collects digits, and places a call to the dialed number. This application is included in Cisco IOS software; you do not have to download it or configure it by using the call application voice command.

The call application alternate command specifies that if the application that is configured in the dial peer fails, the default voice application is executed. If the name of a specific application is entered, that application is triggered if the application configured in the dial peer fails. If the alternate application also fails, the call is rejected.

If an application name is entered, that application must first be configured on the gateway by using the call application voice command.

Examples

The following example configures the DEFAULT application as the alternate:

call application alternate

The following example configures the application session as the alternate:

call application alternate session

Related Commands

Command	Description
application	Enables a voice application on a dial peer.
call application voice	Defines the name of a voice application and specifies the location of the Tcl or VoiceXML document to load for this application.
service	Loads and configures a specific, standalone application on a dial peer.
show call application voice	Displays information about voice applications.

call application cache reload time

---

Note Effective with Cisco IOS Release 12.3(14)T, the call application cache reload time command is replaced by the cache reload time command in application configuration global mode. See the cache reload time command for more information.

---

To configure the router to reload the Media Gateway Control Protocol (MGCP) scripts from cache on a regular interval, use the call application cache reload time command in global configuration mode. To set the value to the default, use the no form of this command.

call application cache reload time bg-minutes

no call application cache reload time

Syntax Description

bg-minutes

Specifies the number of minutes after which the background process is awakened. This background process checks the time elapsed since the script was last used and whether the script is current: •If the script has not been used in the last "unload time," it unloads the script and quits. The unload time is not configurable. •If the script has been used, the background process loads the script from the URL. It compares the scripts, and if they do not match, it begins using the new script for new calls.

Command History

Release	Modification
12.3(8)T	This command was introduced.
12.3(14)T	This command was replaced by the event-log command in application configuration monitor mode.

Usage Guidelines

This command enables event logging globally for all voice application instances. To enable or disable event logging for a specific application, use the call application voice event-log command.

---

Note To prevent event logging from adversely impacting system resources for production traffic, the gateway uses a throttling mechanism. When free processor memory drops below 20%, the gateway automatically disables all event logging. It resumes event logging when free memory rises above 30%. While throttling is occurring, the gateway does not capture any new event logs even if event logging is enabled. You should monitor free memory and enable event logging only when necessary for isolating faults.

Command History

Release	Modification
12.3(8)T	This command was introduced.
12.3(14)T	This command was replaced by the event-log dump ftp command in application configuration monitor mode.

Usage Guidelines

This command enables the gateway to automatically write the event log buffer to the named file either after an active application instance terminates or when the event log buffer becomes full. The default buffer size is 4 KB. To modify the size of the buffer, use the call application event-log max-buffer-size command. To manually flush the event log buffer, use the call application dump event-log command in privileged EXEC mode.

---

Note The call application dump event-log command and the call application event-log dump ftp command are two different commands.

---

---

Note Enabling the gateway to write event logs to FTP could adversely impact gateway memory resources in some scenarios, for example, when:

•The gateway is consuming high processor resources and FTP does not have enough processor resources to flush the logged buffers to the FTP server.

•The designated FTP server is not powerful enough to perform FTP transfers quickly

•Bandwidth on the link between the gateway and the FTP server is not large enough

•The gateway is receiving a high volume of short-duration calls or calls that are failing

You should enable FTP dumping only when necessary and not enable it in situations where it might adversely impact system performance.

---

Examples

The following example enables the gateway to write application event logs to an external file named app_elogs.log on a server named ftp-server:

call application event-log dump ftp ftp-server/:elogs/app-elogs.log username myname 
password 0 mypass

The following example specifies that application event logs are written to an external file named app_elogs.log on a server with the IP address of 10.10.10.101:

call application event-log dump ftp 10.10.10.101/:elogs/app-elogs.log username myname

Command History

Release	Modification
12.3(8)T	This command was introduced.
12.3(14)T	This command was replaced by the event-log error-only command in application configuration monitor mode.

Usage Guidelines

This command limits new event logging to error events only; it does not enable logging. You must use this command with either the call application event-log command, which enables event logging for all voice applications, or with the call application voice event-log command, which enables event logging for a specific application. Any events logged before this command is issued are not affected.

Note Effective with Cisco IOS Release 12.3(14)T, the call application event-log max-buffer-size command is replaced by the event-log max-buffer-size command in application configuration monitor mode. See the event-log max-buffer-size command for more information.

---

To set the maximum size of the event log buffer for each application instance, use the call application event-log max-buffer-size command in global configuration mode. To reset to the default, use the no form of this command.

call application event-log max-buffer-size kilobytes

no call application event-log max-buffer-size

Syntax Description

kilobytes

Maximum buffer size, in kilobytes. Range is 1 to 50. Default is 4.

Command Default

4 kilobytes

Command Modes

Global configuration

Command History

Release	Modification
12.3(8)T	This command was introduced.
12.3(14)T	This command was replaced by the event-log max-buffer-size command in application configuration monitor mode.

Usage Guidelines

If the event log buffer reaches the limit set by this command, the gateway allocates a second buffer of equal size. The contents of both buffers is displayed when you use the show call application session-level command. When the first event log buffer becomes full, the gateway automatically appends its contents to an external FTP location if the call application event-log dump ftp command is used.

A maximum of two buffers are allocated for an event log. If both buffers are filled, the first buffer is deleted and another buffer is allocated for new events (buffer wraps around). If the call application event-log dump ftp command is configured and the second buffer becomes full before the first buffer is dumped, event messages are dropped and are not recorded in the buffer.

---

Note Do not set the maximum buffer size to more than you need for a typical application session. After an active session terminates, the amount of memory used by the buffer is allocated to the history table and is maintained for the length of time set by the call application history session retain-timer command. Also consider that most fatal errors are captured at the end of an event log.

To conserve memory resources, write the event log buffer to FTP by using the call application event-log dump ftp command.

---

Examples

The following example sets the application event log buffer to 8 kilobytes:

call application event-log

call application event-log max-buffer-size 8

Related Commands

Command	Description
call application dump event-log	Flushes the event log buffer for application instances to an external file.

Syntax Description

application-name

Character string that defines the name of the application.

Command Default

The default application is default for all dial peers.

Command Modes

Global configuration

Command History

Release	Modification
12.2(15)ZJ	This command was introduced.
12.3(4)T	This command was integrated into Cisco IOS Release 12.3(4)T.
12.3(14)T	This command was replaced by the global command in application configuration mode.

Usage Guidelines

The application defined in the dial peer always takes precedence over the global application configured with the call application global command. The application configured with this command executes only when a dial peer has no application configured.

The application you configure with this command can be an application other than the default session application, but it must be included with the Cisco IOS software or be loaded onto the gateway with the call application voice command before using this command. If the application does not exist in Cisco IOS software or has not been loaded onto the gateway, this command will have no effect.

---

Note In Cisco IOS Release 12.3(4)T and later releases, the application-name default refers to the applicationCall Admission Control Based on CPU Utilization that supports Open Settlement Protocol (OSP), call transfer, and call forwarding. The default session application in Cisco IOS Release 12.2(13)T and earlier releases has been renamed default.old.c and can still be configured for specific dial peers through the application command or globally configured for all inbound dial peers through the call application global command.

---

Examples

In the following example, the clid_authen_collect application is configured as the global application for all inbound dial peers that do not have a specific application configured:

call application global clid_authen_collect

Related Commands

12.3(14)T	This command was replaced by the interface event-log max-buffer-size command in application configuration monitor mode.

Usage Guidelines

If the event log buffer reaches the limit set by this command, the gateway allocates a second buffer of equal size. The contents of both buffers is displayed when you use the show call application interface command. When the first event log buffer becomes full, the gateway automatically appends its contents to an external FTP location if the call application interface event-log dump ftp command is used.

A maximum of two buffers are allocated for an event log. If both buffers are filled, the first buffer is deleted and another buffer is allocated for new events (buffer wraps around). If the call application interface event-log dump ftp command is configured and the second buffer becomes full before the first buffer is dumped, event messages are dropped and are not recorded in the buffer.

Examples

The following example sets the maximum buffer size to 8 kilobytes:

call application interface event-log max-buffer-size 8

call application session start (global)

---

Note Effective with Cisco IOS Release 12.3(14)T, the call application session start (global) command is replaced by the the session start command in application configuration mode. See the session start command for more information.

---

To start a new instance (session) of a Tcl IVR 2.0 application, use the call application session start command in global configuration mode. To stop the session and remove the configuration, use the no form of this command.

call application session start instance-name application-name

no call application session start instance-name

Syntax Description

instance-name	Alphanumeric label that uniquely identifies this application instance.
application-name	Name of the Tcl application. This is the name of the application that was assigned with the call application voice command.

Command Default

This command has no default behavior or values.

Command History

Release	Modification
12.3(4)T	This command was introduced.
12.3(14)T	The call application session start (global configuration) command was replaced by the session start command in application configuration mode.

Usage Guidelines

This command starts a new session, or instance, of a Tcl IVR 2.0 application. It cannot start a session for a VoiceXML application because Cisco IOS software cannot start a VoiceXML application without an active call leg.

You can start an application instance only after the Tcl application is loaded onto the gateway with the call application voice command.

If this command is used, the session restarts if the gateway reboots.

The no call application session start command stops the Tcl session and removes the configuration from the gateway. You can stop an application session without removing the configuration by using the call application session stop command.

VoiceXML sessions cannot be stopped with the no call application session start command because VoiceXML sessions cannot be started with Cisco IOS commands.

If the application session stops running, it does not restart unless the gateway reboots. A Tcl script might intentionally stop running by executing a "call close" command for example, or it might fail because of a script error.

You can start multiple instances of the same application by using different instance names.

Examples

The following example starts a session named my_instance for the application named demo:

call application session start my_instance demo

The following example starts another session for the application named demo:

call application session start my_instance2 demo

Usage Guidelines

This command starts a new session, or instance, of a Tcl IVR 2.0 application. It cannot start a session for a VoiceXML application because Cisco IOS software cannot start a VoiceXML application without an active call leg.

You can start an application instance only after the Tcl application is loaded onto the gateway with the call application voice command.

Using this command does not restart the session if the gateway reboots. To automatically restart the session if the gateway reboots, use the call application session start command in global configuration mode.

To stop an application session once it starts running, use the call application session stop command.

If the application session stops running, it does not restart unless the gateway reboots and the call application session start command is used in global configuration mode. A Tcl script might intentionally stop running by executing a "call close" command for example, or it might fail due to a script error.

You can start multiple instances of the same application by using different instance names.

Examples

The following example restarts an application session called my_instance:

call application session start my_instance

call application session stop

To stop a voice application session that is running, use the call application session stop command in privileged EXEC mode.

call application session stop {callid call-id | handle handle | id session-id | name instance-name}

Syntax Description

callid call-id	Call-leg ID that can be displayed in the output from the debug voip ivr script command if the Tcl script uses puts commands.
handle handle	Handle of a session from the Tcl mod_handle infotag.
id session-id	Session ID that can be displayed with the show call application sessions command.
name instance-name	Instance name that was configured with the call application session start command.

Command Default

None

Command Modes

Privileged EXEC

Command History

Release	Modification
12.3(4)T	This command was introduced.

Usage Guidelines

This command stops a Tcl IVR 2.0 or VoiceXML application session that is identified by one of four different methods: call ID, handle, session ID, or instance name. To see a list of currently running applications, use the show call application sessions command.

A Tcl session that is stopped with this command receives a session terminate event. The session is expected to close all call legs and stop. If a session does not close itself after a 10-second timer, it is forcibly stopped and all call legs that it controls disconnect.

Using this command to stop a VoiceXML session immediately stops the document interpretation and disconnects the call leg. No VoiceXML events are thrown.

If you stop a Tcl session that is configured to start with the call application session start command in global configuration mode, you must remove the session by using the no call application session start command before you can restart it.

To see a list of stopped sessions, use the show call application sessions command. Only stopped sessions that are configured to start with the call application session start command in global configuration mode are displayed. If a session was started with the call application session start command in privileged EXEC mode, it is not tracked by the system and it is not shown as stopped in the output of the show call application sessions command.

Examples

The following example stops an application session called my_instance:

call application session stop name my_instance
