The main missing parts, the last time i had a look at the problems are: - support for UDPTL in mod_sofia that lacks the code to parse and generate it - (eventually add t.38 over RTP in mod_sofia, but i have not yet seen any commercial/free switch that does manage it) - rework switch_rtp to accept t.38 packets to an application. - A way to signal an application that the channel supports T.38 (because, for example, mod_fax can be used on wanpipe - no t.38 and on sip) - A way to force a switchover to t.38, sent from the application to the channel driver (if supported) (because mod_fax may request a t.38 switchover to sofia or t38gw may request one leg to switch to t.38) - A way to signal the application that a switchover to T.38 has occurred on the channel driver (because the remote party may switch to t.38 and the endpoint application must take care of this) For the last 3 points, i have no idea how to do it in a clean and elegant way.
