Cisco Cisco IOS Software Release 12.2(2)XA

To define the call agent for an MGCP profile, use the call-agent MGCP profile command. 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]

The default call-agent UDP port is 2727 for MGCP 1.0, NCS 1.0, and TGCP 1.0.

The default call-agent UDP port is 2427 for MGCP 0.1 and SGCP.

The default service type and version is mgcp 0.1.

MGCP profile configuration

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 DNS name rather than 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 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. 

Fully qualified domain name (including host portion) for the call agent. For 
example, ca123.example.net.

IP address of the call agent.

UDP port number over which the gateway sends messages to the call agent. 
Range is from 1025 to 65535.

Keyword indicating that the next word is the protocol service type.

Protocol service type. Valid values are mgcp, ncs, sgcp, and tgcp.

Keyword indicating that the next word is the version number.

Protocol version. Valid values are:

For service-type mgcp: 0.1, 1.0

For service-type ncs: 1.0

For service-type sgcp: 1.1, 1.5

For service-type tgcp: 1.0
