The place to debug this is on the end receiving the call. All you see on the calling side is that the call was disconnected, and the reason code is an Q931 error code which going to be something generic. When you debug the other end, you can see more information. You may need to debug more than Q931 on the receiving side, such as "aaa authentication", "ppp negotiation", etc. to find out why it is terminating the call.
