MGCP Configuration
Configure parameters for the voice interface.
Step 2
a.
b.
c.
Configure the PRI port by entering the following command:
Step 3
Gateway(controller-e1)# pri-group timeslots 1-31 service mgcp
Bind Layer 3 to the Cisco CallManager for PRI Q.931:
Step 4
Gateway(config-if)# isdn bind-l3 ccm-manager backhaul q931
This command backhauls (tunnels) ISDN Layer 3 and above to the
Cisco CallManager.
PRI/Q.931 signaling backhaul transports signals (Q.931 and higher layers) for
processing a PRI trunk that is physically connected to an MGCP call agent.
The ISDN lower layer information (Q.921 and below) is terminated and processed
on the gateway. The Layer 3 information (Q.923 and above) is transported over
TCP to the Cisco CallManager (MGCP call agent).
Enable MGCP for the port by entering the following commands:
Step 5
Gateway(config)# dial-peer voice 1 pots
Gateway(config-dial-peer)# application mgcpapp port
<portnumber>:<ds0group>
Replace portnumber with the port number on the voice gateway you are
configuring and ds0group with the DS0 group number.
To view the status of the PRI line, enter the following command:
Step 6
Gateway# show ccm-manager backhaul
