[Freeswitch-users] Detect T.38 reinvite and transcode?

Hi there, Is there a way to have FreeSWITCH detect a T.38 reinvite, accept it, and transcode that into ULAW before sending it on to the B-leg? The fax is neither originated nor terminated on the FS gateway. FS would simply transcode T.38 to ULAW. I looked at the mod_spandsp documentation and it wasn't readily apparent. To be clear host_a -> FS -> host_b host_a sends an INVITE host_b responds with 100, 180, 200 then host_a sends another INVITE with SDP for T.38 Can FS ack that RE-INVITE and transcode, so the legs look like this? host_a -> T.38 -> FS -> ULAW -> host_b Thanks!
