MGCP registration

Steellllllllll0 · ‎07-22-2008

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 Admin State ACTIVE, Oper State ACTIVE - Cause Code NONE

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

have u made a pots dial-peer for mgcp

lets say ur port number is 1/0/0

dial-peer voice 1 pots

application MGCPAPP

port 1/0/0

Steellllllllll0 · ‎07-22-2008

Hi,

I have not created any dial-peers....is this not something that is downloaded in the xml file from the ccm ???

Marwan ALshawi · ‎07-22-2008

try it then let me know

dial peer same as the one above

Steellllllllll0 · ‎07-22-2008

Hi,

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

Marwan ALshawi · ‎07-22-2008

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

Have you tried using the command

dial-peer voice 100 pots

service mgcp

i think service mgcp or application mgcp

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

right?

Ayodeji Okanlawon · ‎07-22-2008

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.
