[cisco-voip] T.38 fax cisco- patton

[Teodor Georgiev]

	       Brian,
 
  you haven't provided enough info on your subject. IMHO, An H245 trace would 
show a lot. A copy of the config at both sides + an explanation what is not 
working on 100% would help a lot.

The T.38 interopability is really pain in the neck, because some gateways have 
implemented different techniques. The Cisco T38 implementation drops the 
current RTP port settings and starts a renegotiation once it sees a T.38 
request. Another issue is that the Cisco T38 implementation supports merely 
UDP as a transport protocol. You should request more information from Patton 
also.
