[Dennis Mink]

please start by cleaning up your dial peers. you dont need and incoming called number on all dial peers. only a single one will do when receiving calls. I think that is where your issue is: T302/interdigit timeout.

best way to find out is make a call and debug dial peer and see who long it takes for the call to finally resolve a destination.
