I have a new deployment with RightFax 9.3 and Callmanager 6.1. The gateway is a CMM module off of a 6509 and it uses MGCP to communicate with the CUCM. An ICT is setup between CUCM and the RightFax server. I set up a RP to point incoming DID calls to the RightFax and I see it landing on the channels of the fax server but after three seconds of fax tone, the call drops. I did a wireshark trace and it gives a "H225 Q931 Rel Cause (65): Bearer capability not implemented". What exactly does this mean? Is it because there's an error in the T.38 of the gateway or is it because I'm not calling the server with a fax machine. I was trying to test incoming calls by dialing with my phone. Conversely, any call out from the RightFax doesn't even hit the gateway. Calls get a "unallocated number" reason code in Wireshark.
