[Freeswitch-users] BEHAVIOR CHANGE (YES PAY ATTENTION TO THIS IF YOU USE FAXING)

Tue Mar 28 21:09:45 MSD 2017

Its not coded to even react and activate T.38 on an initial invite.  You'll
have to talk to your vendor about that fax server thats sending the call, I
do not believe that particular way worked in previous releases either.
