[Freeswitch-users] fax relay question

[Darcy Primrose]

We use a freeswitch as a relay between our carriers and other freeswitches, it has worked great until we upgraded to the latest  freeswitch version recently
We we receive a fax, inbound and relay it, the subsequent re invite we get back looks like the frist block below, then when the freeswitch relays it, it adds 
in " Media Description, name and address (m): audio 0 RTP/AVP 19".  The originating carrier sees this and responds with audio instead of T38, the call drops.

Any hints would be greatly appreaciated,  I do not really want to go back to a previous release if I can avoid it.
