MGCP Configuration
MGCP Configuration
When using Cisco IOS Release 12.1(3)T and higher software image s that support voice, the
CiscouBR924 router can use the MGCP protocol for routing voice calls. This transfers the dial mapping
to an external call agent or to a Media Gateway Controller, so that the VoIP gateways do not have to be
individually configured with the dial mappings.
Note The Cisco uBR924 router can use MGCP in either DOCSIS-bridging mode or routing mode.
You must do the following to configure the Cisco uBR924 router for MGCP routing of voice calls:
•Enable MGCP operation on the Cisco uBR924 router.
•Specify the MGCP call agent’s IP address.
•Configure the local dial-peers to be MCGP applications.
•Optionally specify the MGCP packages to be supported.
•Optionally change a number of MGCP parameters.
Note No configuration of remote dial-peers is needed when using MGCP.
These functions are done using the commands shown in the following table:
Command Purpose
Step1 To configure incoming calls on voice port V1:
uBR924(config)# dial-peer voice id-number pots
Specify a unique id-number for this incoming
dial-peer and enter dial-peer configuration mode.
Step2 uBR924(config)# application MGCPAPP Specify that this dial-peer is handled as an MGCP
application.
Step3 uBR924(config-dial-peer)# port 0 Specify that voice port V1 is attached to this
telephony equipment.
Step4 uBR924(config-dial-peer)# exit Exit dial-peer configuration mode.
Step5 To configure incoming calls on voice port V2:
uBR924(config)# dial-peer voice id-number pots
Specify a unique id-number for this incoming
dial-peer and enter dial-peer configuration mode.
Step6 uBR924(config)# application MGCPAPP Specify that this dial-peer is handled as an MGCP
application.
Step7 uBR924(config-dial-peer)# port 1 Specify that voice port V2 is attached to this
telephony equipment.
Step8 uBR924(config-dial-peer)# exit Exit dial-peer configuration mode.
Step9 ubr924(config)# mgcp Enable MGCP operations on the router.
Step10 ubr924(config)# mgcp call-agent ip-address [ port ]
[service-type sgcp | mgcp ]
Specify the IP address and optional UDP port
number for the MGCP call-agent. If no port number
is given, the default is 2427. The default
service-type is mgcp, but sgcp can be specified to
ignore RSIP error messages.
