Strange issue with 12.4 and MGCP.

Hi ,

I have an issue dialing out from an mgcp router using 12.4 version. The issue is that the call rings at the destination phone and the same IP phone too receives the same call. After a while both the phones busy out....very strange

Now using the same configuration when I jst boot the router with IOS version 12.3(14)T all works perfectly well.

Any suggestions ??

Sounds like a bug to me. Which series of routers are using and what's the CCM version?

Re: Strange issue with 12.4 and MGCP.

try to put in mgcp package line. i think this is not default in 12.4. in the T train it must be default.. I see that the port actually unregisters:

Oct 11 07:56:51.957: cmapp_host_fsm: New state DOWN for host 0 (

Also, I am not seeing the MGCO created dial-peers for the other voice ports. Are all the voice ports configured on the CCM side?

WHat version of IOS exactly, and can you post a debug mgcp packet for a problem call also?
