Summary:                    [patch] T38 support for SendFax/ReceiveFax
Description: 
Adding T38 support to SendFax/ReceiveFax applications. See Additional
Information for details.

There are two patches:
* appfax-v3.patch for asterisk-addons/trunk rev 497 - modifications to the
fax application
* asterisk-t38.patch - temporary (see below) patch for asterik/trunk
revision 94396

!IMPORTANT NOTE! This patch is considered work in progress because it
depends on not yet finished feature of Asterisk - ability to request T38
reinvite on a SIP channel.
Currently, the patch adds this ability itself (asterisk-t38.patch) but it
adds it in a very rude way. It is clearly a hack. When file finishes his
t38insanity branch and Aterisk will get official way of requesting
re-invite, I will update app_fax to use that way instead and
asterisk-t38.patch won't be needed anymore.

oej,
actually, currently I have a big gap in debug levels between 8 and 20
which does not change anything so of course I can move logging I do at
level 20 to the level 10. No problem.
However, I chosen 20 intentionally - currently at the level 20 every
received frame gets logged which produces flood on the console. So I chosen
high level to save user from turning it on accidently. If it is Ok to have
this happining on the level 10, I will adjust the code appropriately.
I'm not sure if separate T38 logging is needed because in case you
troubleshooting something, you will need sip+rtp+udptl debugging anyway.


slavon,
No, I'm not going to backport the application to 1.4 because the whole
idea why I created SendFax/ReceiveFax application is to offer people
_supported_ application which they get from official SVN and which chages
appropriately to match changes in Asterisk code. Since 1.4 version won't be
accepted by Digium there is no way to provide support for it - make and
publish fixes etc.
However backporting is very easy to do. Please either contact Cache who
already did it (I believe you know him) or do the patch yourself.
