Unanswered Question
Jul 22nd, 2008

Hi Guys,

I am setting up a couple of fxo ports on an mgcp gateway and for some reason cannot get the ports to register. Here is some output from :

access-hcmc-cs#sh mgcp

MGCP call-agent: none Initial protocol service is MGCP 0.1

MGCP validate call-agent source-ipaddr DISABLED

MGCP dtmf-relay for VoIP is SDP controlled

MGCP dtmf-relay for voAAL2 is SDP controlled

MGCP voip modem passthrough disabled

ccm-manager mgcp

ccm-manager config server

ccm-manager config

access-hcmc-cs#sh ccm-manager

I can ping the ccm successfully from the gateway and checked the host names etc are a 100% match....any ideas ??

The application mgcpapp is not a valid command under the dial-peer....wont allow it...

you need to bind MGCP to the voice ports. You do this by configuring a dial peer for each voice port and binding MGCP to it using the application MGCPAPP command. This command is case sensitive in some IOS releases. To be safe, code MGCPAPP (all capital letters) unless you know that your release is not case sensitive.

VoiceGW(config)#dial-peer voice 100 pots

VoiceGW(config-dial-peer)#application MGCPAPP

VoiceGW(config-dial-peer)#port 1/0/0

When you make a change to the MGCP configuration, such as adding or changing endpoints, it is a good idea to reinitialize MGCP by issuing no mgcp and then mgcp global configuration commands

try it agin

and good luck

hope this helpful

i think service mgcp or application mgcp

he should tell the port that its controlled by the mgcp-agent

The service mgcp, enables the MGCP application on the pots dial-peer.

Although in newer versions of IOS, it is not required. It is just safe to have it there

Pls place output "show running | inclu mgcp" from your rtr.

The output of 'show mgcp' indicated:


MGCP call-agent: none


It appears no call-agent defined for mgcp.
