2821 MGCP not registering with CCM 4.1

Hello, I am trying to get an E1 Q.sig up but the gateway just won't register with the Call Manager, here is the relevant config being used:

controller E1 0/0/0

pri-group timeslots 1-31 service mgcp

interface Serial0/0/0:15

no ip address

no logging event link-status

isdn switch-type primary-qsig

isdn incoming-voice voice

isdn bind-l3 ccm-manager

isdn bchan-number-order ascending

no cdp enable

mgcp

mgcp call-agent 172.23.2.5 2427 service-type mgcp version 0.1

mgcp dtmf-relay voip codec all mode out-of-band

When issuing the show ccm-manager command I get this:

Re: 2821 MGCP not registering with CCM 4.1

can you post a screenshot of your CCM config?

i suspect that the MGCP name in CallManager is not AFIGW2821.yourdomain.com

You should either remove the domain name in the gateway or make it correct and use the full name in the CCM configuration.

Re: 2821 MGCP not registering with CCM 4.1

That did it. Removing the domain name on the router allowed it to register inmmediattly.

thanks!
