I have a Mediatrix talking H.323 to Cisco 7960 via Cisco Call Manager v3.2.1. Cisco 7960 can establish a voice call with Mediatrix as long as Cisco initiates the call.
When Mediatrix initiates the call, Cisco reject the H.225 call setup with the following.

Does anyone know based on this trace which part of the header is not accepted by Cisco? The called number should be valid.
