[asterisk-dev] trying to port t38 gateway patch to svn revision 222535

[Niccolò Belli]

Hi!
I'm trying to port t38 gateway patch to asterisk 1.6.2, but I'm not a
developer and so I'm not sure of what I'm doing.
This is the original patch: http://darkbasic.homelinux.com/t38-gw-r205116.patch
and this is the one modified by me:
http://darkbasic.homelinux.com/t38-gw-r222535.patch

It compiles flawlessly, but I get some errors when I try to send faxes:

      > requested prefs = (),

Can someone help me? I need the t38 gateway feature in a asterisk 1.6.2 box...
