Summary:                    1.4 Passthru Receives T38 Re-Invite and passes on a
non-T38 invite to other peer.
Description: 
INCOMING Fax from PSTN. ENSR has full T38 Gateway support.

Analogue fax -> PSTN -> ENSR2.5.4 -> Ast1.4.37 -> Ast1.6.1.20

The problem happens when 1.6 re-invites with a T38 Offer to 1.4. 
1.4 see's the T38 offer (and sends TRYING to 1.6), but re-invites to ENSR
with G711 instead of T38.

Upon close inspection of the Debug log, Asterisk sends TRYING and then
chooses to "DEFER" sending the T38 re-invite to ENSR. What happens after
that, I'm not exactly sure.

---------------------------------------------------------------------- 
Since I don't have your setup (and can't replicate it), could you send me
the log file of Asterisk (debug & sip debugging enabled) + a pCAP trace of
the network traffic?
I really need it in order to figure out whats happening..
