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

[Bill W.]

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!
Bill
