2811 Router will not Register to CallManager MGCP

[NPT_2]

Has anyone had any luck getting a 2811 router to register via MGCP to Callmanager. I am running 4.12 ES03 callmanager and the latest 12.3(11)T2 code on the 2811. The router never completes registration and debugs for errors on ccm and mgcp show the following:

Dec 21 23:47:59.618: cmapp_mgr_process_ev_active_host_failed: Active host 0

(17

2.16.1.20) failed

*Dec 21 23:47:59.618: mgcp_endpt_get_call_record: null pointer specified for

end

point.

*Dec 21 23:48:29.618: cmapp_mgr_process_ev_active_host_failed: Active host 1

(17

2.16.1.15) failed

*Dec 21 23:48:29.618: cmapp_mgcpapp_go_down: Setting mgc status to

NO_RESPONSE

*Dec 21 23:48:29.618: mgcp_endpt_get_call_record: null pointer specified for

end

point.

also in the callmanager even logs I get the following:

Error: DeviceTransientConnection - Transient connection attempt.

This occurs over and over again. I have a TAC case open but they have yet to come up with a solution. Any thoughts? All my other routers are registering fine with MGCP.

Does the DOMAIN Name in Call manager for this gateway match the routers domain name exactly?

In the event log, the domain name being sent from router should be in the error.

Can you post the CCM MGCP domain name, as well as the router host and domain name configuration?

The router will combine the host and domain name to get the domainname it sends to ccm for registration.

Router config:

hostname AVVID_RTR

ip domain name avvid-rocks.com

MGCP domain name sent: AVVID_RTR.avvid-rocks.com

Only way to see this is with 'debug mgcp packet'

2w1d: send_mgcp_msg, MGCP Packet sent --->

2w1d: RSIP 1 aaln/S1/SU0/0@AVVID_RTR.avvid-rocks.com MGCP 0.1

RM: restart

<---

Router config:

hostname AVVID_RTR

(no IP Domain name configured)

MGCP domain name sent: AVVID_RTR

You are right, it turns out I was not using the dns name in my callmanager gateway config, but I did have it configured on the router with a ip domian name command. Once I added the domain to the config everything is working fine.

I am running CCM 4.0(2a)sr1, and I do have a 2811 registered using MGCP. Here are the things in the router pertinent to MGCP. I hope this helps.
