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 ya new patch will be out soon ill be in richards bay for 2 days [see if
there is any one who can find it on a map.ill be doing a asterisk
installation if there is a map in Digium HQ put a pin there im ammased
there are E1 provisioned] so working furiously at it at the moment.

please note this patch like all new features is for TRUNK the f->data is
indeed f->data.ptr in trunk.

the LOAD_OH hunk / channel locking sliped in unnoticed from 1.4 humblist
appologies.

one of the changes ive added and am testing is a ast_generator on the T.30
channel to handle the frame creation.

also taken a few liberties on the actual gateway loop...

also am checking AST_LIST_NEXT im not sure if it is needed or even correct
...
