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.

----------------------------------------------------------------------
hello
I am trying to make your patch work with the following setup
ATA -> SIP/T.38 -> Asterisk -> DAHDI -> FAX
The ATA is an Grandstream HT502 with the latest Firmware , tested others.
asterisk is 1.6.2.6 with the latest dahdi and libpri.
Everything seem to go well, but when the connections dies before the FAX
is transmitted.
here is a part of the console log :
