Wierd MGCP gateway problem

When a calls exit one particular MGCP gateway the remote phone rings, but when they answer noone is there. If they don't hang up, the router drops the call. The gateway is a 1760 with a vic2-4fxo. All this time the IP phone hasn't heard the first ring-back. Then at 30 seconds into the call, the IP phone rings the remote phone and if they answer, the call continues normally. I've attached some logs of the event occuring. I've backed off from 12.3.4T2 back down to 12.3.4T, but that didn't make any difference. I've also forced it to register with the backup call-manager, but that didn't have any effect either. I'm probably going to configure it for h323 mode tonight to see if that changes things.

Has anyone seen this before?

Try adding the 2 mgcp bind commands (for media and signalling in main config mode - you may have an inconsistency with the IP address the gateway registered with and the address the traffic is being sourced from.
