The show commands are useful for displaying the current status of the configuration as well as verifying that the changes that you made took effect. The following commands are described:
- show ccm-manager
- show mgcp
- show mgcp endpoint
- show mgcp connection
- show voice port mod_num/slot_num/port_num
- show mgcp statistics
- Other debug mgcp Commands
show ccm-manager
If your MGCP network includes Cisco CallManager, use this command to verify the active and redundant configured Cisco CallManager servers. This command also indicates if the gateway is currently registered with Cisco CallManager. | Note: | The following show ccm-manager command output was captured in a separated environment. |

show mgcp endpoint
Use this command to show the voice ports (endpoints) that are under MGCP control in the router. This command verifies which voice ports have been bound to the MGCP application. This is related to the application mgcp command and the port commands that were entered when configuring the POTS dial peer.VG200A#show mgcp endpoint voice-port 1/0/0 voice-port 1/0/1 voice-port 1/1/0 voice-port 1/1/1 VG200A#
show mgcp connection
Use this command to display any active MGCP connections. The endpoint in this example is Slot1/Module 1/Port 0. This corresponds to the MGCP Member Configuration identifier in Cisco CallManager. This tells you which port on the router is the endpoint in the call.In the screen output below there is one active call.
