2821 MGCP Ungregistered after SSH enable ip domain-name

Unanswered Question

I upgraded all of 6 my 2821 Voice Gateway routers to 12.4(11)XW3 to prepare for more secure SSH access.

In order to enable SSH I input ip domain-name.

I noticed that CallManager displayed unregistered for these MGCP controlled E1 controllers.

I removed the ip domain-name and the gateways re-registered with CallManager.

Has anyone an answer to this please?

Hi Kim,

The Domain name issue is outlined nicely in this doc;

MGCP Gateway Registration Failure with Cisco CallManager


If the IP domain name is configured in Cisco IOS on the MGCP gateway, enter the Fully Qualified Domain Name (FQDN) in the Domain Name field.

In the example: test and cisco.com represent the hostname and domain name respectively. If the IP domain name is not configured in Cisco IOS on the MGCP gateway, enter only the hostname of the MGCP gateway in the Domain Name field.

You would enter test.cisco.com (in CCM)

Hope this helps!
