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.

irroot, thank you! I had not res_fax.

But, now, asterisk segfaults right after fax on far side accept call:

    -- DAHDI/i1/5308-1 is proceeding passing it to
OOH323/192.168.22.253-9
    -- DAHDI/i1/5308-1 is making progress passing it to
OOH323/192.168.22.253-9
    -- DAHDI/i1/5308-1 is ringing

and then segfault.

Program terminated with signal 11, Segmentation fault.

If I remove exten => 4406,1,SET(FAXOPT(t38gateway)=yes) all is OK.

btw, this is centos 5.6 on x86-64.
