Summary:                    [patch] T38 gateway
Description: 
Hi all,

I'm sending you patch containing new application app_faxgateway.c
("FaxGateway") which is able to mediate T30 to T38 and vice versa.
Feature is using spands library (I used spandsp-0.0.4pre18 and
spandsp-0.0.5pre4).

Best regards
Daniel.

Looks like Grandsream gets confused about the T38 packets and closes the
call. May Grandstream does not support forward error correction (FEC) mode
(although it announces it in the SDP). Try redundancy mode in sip.conf,
e.g:
t38pt_udptl = yes,redundancy,maxdatagram=400
