Summary:                    [patch] Improvements/fixes for app_fax
Description: 

I was working on a backport of app_fax to asterisk 1.4 branch.

It works great now, but the original code was causing errors to be logged
(a new issue as of 1.4.24, see bug id http://bugs.digium.com/view.php?id=14723).
As I looked into the code
more I found what I think a problems/bugs. Here is a patch (for 1.6 trunk)
for my "improvements/fixes".

I'm using SPANDSP 0.0.6pre7 and testing with SIP using an external PSTN
gateway (AS5300). I can send a fax from the system to the same system
(using the PSTN), so it seems happy. I also tested with a normal fax
machine. RX works way better than TX for me.

It never worked before - with none of my T.38 capable gateways (Cisco 2821,
5350, Innovaphone ip400, ip800). So maybe your current efforts to make T.38
work with app_fax may fail because of some other (indirect) problem.
