Cisco IOS Voice Commands:
K
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 Guide.
keepalive retries
To set the number of keepalive retries from Skinny Client Control Protocol (SCCP) to Cisco Unified CallManager, use the keepalive retries command in SCCP Cisco CallManager configuration mode. To reset this number to the default value, use the no form of this command.
keepalive retries number
no keepalive retries
Syntax Description
number |
Number of keepalive attempts. Range is 1 to 32. Default is 3. |
Command Default
3 keepalive attempts
Command Modes
SCCP Cisco CallManager configuration
Command History
|
|
|
|---|---|
12.3(8)T |
This command was introduced. |
Usage Guidelines
Use this command to control the number of keepalive retries before SCCP confirms that the Cisco Unified CallManager link is down. When SCCP confirms that the Cisco Unified CallManager link is down (if the number of keepalive messages sent without receiving an Ack reaches the keepalive retries value), Cisco Unified CallManager switchover is initiated.
Note 
The optimum setting for this command depends on the platform and your individual network characteristics. Adjust the keepalive retries to meet your needs.
Examples
The following example sets the number of times that a Cisco Unified CallManager retries before confirming that the link is down to seven:
Router(conf-sccp-ccm)# keepalive retries 7
Related Commands
keepalive target
To identify Session Initiation Protocol (SIP) servers that will receive keepalive packets from the SIP gateway, use the keepalive target command in SIP user-agent configuration mode. To disable the keepalive target command behavior, use the no form of this command.
keepalive target {{ipv4:address | ipv6:address}[:port] | dns:hostname} | [tcp [tls]] | [udp] | [secondary]
no keepalive target [secondary]
Syntax Description
Command Default
No keepalives are sent by default from SIP gateway to SIP gateway. The SIP port number is 5060 by default.
Command Modes
SIP user-agent configuration (config-sip-ua)
Command History

|
|---|---|
12.4(6)T |
This command was introduced. |
12.4(22)T |
Support for IPv6 was added. |
Usage Guidelines
The primary or secondary SIP server addresses are in the following forms: dns:example.sip.com or ipv4:172.16.0.10.
Examples
The following example sets the primary SIP server address and defaults to the UDP transport:
sip-ua
keepalive target ipv4:172.16.0.10
The following example sets the primary SIP server address and the transport to UDP:
sip-ua
keepalive target ipv4:172.16.0.10 udp
The following example sets both the primary and secondary SIP server address and the transport to UDP:
sip-ua
keepalive target ipv4:172.16.0.10 udp
keepalive target ipv4:172.16.0.20 udp secondary
The following example sets both the primary and secondary SIP server addresses and defaults to the UDP transport:
sip-ua
keepalive target ipv4:172.16.0.10
keepalive target ipv4:172.16.0.20 secondary
The following example sets the primary SIP server address and the transport to TCP:
sip-ua
keepalive target ipv4:172.16.0.10 tcp
The following example sets both the primary and secondary SIP server addresses and the transport to TCP:
sip-ua
keepalive target ipv4:172.16.0.10 tcp
keepalive target ipv4:172.16.0.20 tcp secondary
The following example sets the primary SIP server address and the transport to TCP and sets security to TLS mode:
sip-ua
keepalive target ipv4:172.16.0.10 tcp tls
The following example sets both the primary and secondary SIP server addresses and the transport to TCP and sets security to the TLS mode:
sip-ua
keepalive target ipv4:172.16.0.10 tcp tls
keepalive target ipv4:172.16.0.20 tcp tls secondary

keepalive timeout
To set the length of time between keepalive messages from Skinny Client Control Protocol (SCCP) to Cisco Unified CallManager, use the keepalive timeout command in SCCP Cisco CallManager configuration mode. To reset the length of time to the default value, use the no form of this command.
keepalive timeout seconds
no keepalive timeout
Syntax Description
seconds |
Time between keepalive messages. Range is 1 to 180. Default is 30. |
Command Default
30 seconds
Command Modes
SCCP Cisco CallManager configuration
Command History
|
|
|
|---|---|
12.3(8)T |
This command was introduced. |
Usage Guidelines
Whenever SCCP sends the keepalive message to the Cisco Unified CallManager, it initiates this timer. Once the timeout occurs, it sends the next keepalive message unless the number of keepalive (messages without an Ack) reaches the number set by the keepalive retries command. As of now, the SCCP protocol uses the value provided by the Cisco Unified CallManager.
Note The optimum setting for this command depends on the platform and your individual network characteristics. Adjust the keepalive timeout value to meet your needs.
Examples
The following example sets the length of time between Cisco Unified CallManager keepalive messages to 120 seconds (2 minutes):
Router(config-sccp-ccm)# keepalive timeout 120
Related Commands
keepalive trigger
The trigger interval (in seconds) represent the number of Options message requests that must consecutively receive responses from the SIP servers when in the down state in order to unbusy the voice ports, use the keepalive trigger command in SIP UA configuration mode. To restore to the default value of 3 seconds, use the no form of this command.
keepalive trigger seconds
no keepalive trigger seconds
Syntax Description
seconds |
Keepalive trigger value in the range from 1 to 10 seconds. The default value is 3 seconds. |
Command Default
The default value for the keepalive trigger is 3 seconds.
Command Modes
SIP UA configuration
Command History

12.4(6)T |
This command was introduced. |
Usage Guidelines
Sets the time interval (in seconds) to represent the number of Options message requests that must be consecutively receive responses from the SIP servers in order to unbusy the voice ports when in the down state. The keepalive trigger interval is measured in seconds. The default is 3 seconds.
Examples
The following example sets a time interval (in seconds) after the number of Options message requests that must consecutively receive responses from the SIP servers in order to unbusy the voice ports when in the down state. The trigger interval is set to 8 seconds in the following example:
sip-ua
keepalive trigger 8
