-    [mod-sofia] Fix reINVITE after T38 is rejected
-    
-    From FS-11833.
-    
-    After FS sends a reINVITE to T38 which gets rejected by peer it is no
-    longer in a state where it can properly answer a reINVITE which requests
-    a change of the media setup.
-    
-    1. FS sends INVITE (destination is a fax machine)
-    2. Call connects with "8 101"
-    3. FS sends reINVITE to T38
-    4. T38 rejected (488)
-    5. FS receives INVITE to "8"
-    6. FS replies with 200 OK without SDP
-    7. Call fails
-    
-    The bug is related to TFLAG_SDP. This flag is set when a media session
-    is established. And when there's a reINVITE sofia_glue_do_invite() from
-    sofia_glue.c is called and clears the flag again:
-    
-    sofia_clear_flag_locked(tech_pvt, TFLAG_SDP);
-    
-    So when FS sends a reINVITE to T38 the flag gets cleared. But when the
-    reINVITE is rejected with 488 the flag is not set again. It stays
-    cleared. So the call continues with the previously negotiated media, fax
-    passthrough (8 101 in this case), but TFLAG_SDP is not set.
-    
-    So when FS receives a reINVITE at this point it doesn't see the need to
-    renegotiate anything, even though it realizes that 2833 DTMF is now off:

-    
-    When FS doesn't send a reINVITE (fax_enable_t38_request=false) and the
-    reINVITE to "8" is received, TFLAG_SDP is still set and then FS
-    understands that it needs to renegotiate and replies with a 200 OK that
-    includes SDP:

-    This fixes the state problem after a rejected T38 reINVITE by setting
-    TFLAG_SDP.
