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.

@dluzin: thanks for your input, although I don't understand part of it. Did
you mean "asterisk 1.6.13 No 2" instead of the second "asterisk 1.4.21 with
udptl" ?

You did remind me on some way for doing this like:

Fax1 <-> ATA1 <-SIP/T.38-> Asterisk1 <-RTP-> Asterisk2 <-SIP/T.38-> ATA2
<-> Fax2

I tryed this by creating a SIP trunk in both directions between Asterisk1
and Asterisk2 and declaring the t38pt_udptl=no in each of them, is this the
way to force the Asterisk to not use T.38?

I tested this on both directions and the results were the same: Asterisk
of the caller negotiates T.38 with the caller but the other Asterisk
doesn't negotiate T.38 with the callee. Don't know what I am doing wrong
here...

Regarding the ATAs, I tryed before a GrandStream HT286 and some Draytek
(don't remember the model) and the results were not satisfatory... the only
good ones that I had were with the Planets VIP-157s.

Any help appreciated and thanks for your time
