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.

Hi there. I've tested the patch as well (thanks a lot to its author) and
faced the same issue(t.38 reinvite, 5 seconds and '488 not acceptable').
This annoying problem existed before patch and hopefully will be fixed
under https://issues.asterisk.org/view.php?id=16793 or
https://issues.asterisk.org/view.php?id=16327

With the t.38 gateway patch, it starts gateway application, but due to the
mentioned bug, it disconnects in 5 seconds.
