MGCP gateway not registering

I can NOT get my MGCP gateways to register with callmanager. I know the CM needs to be able to resolve the name, but it doesnt specify to which interface. Right now it resolves to loopback 0, but yet I see the router initiating a tcp session to CM from the serial interface. Is that possibly the issue?

Re: MGCP gateway not registering

config this on the interface you want, look at the example

mgcp bind control source-interface FastEthernet0/1

mgcp bind media source-interface FastEthernet0/1

Re: MGCP gateway not registering

Thats what I was looking for!

Oddly enough I decided to reload the router and it came up and my endpoints registered with out the command though. Bizzare.

Only thing I cant do now is call out on my FXS station, but I can call in to it.
