We know for a fact that Asterisk has no trouble with the signaling and 
media going to different addresses/ports. Honestly, I just don't 
understand why all of this effort is being put into trying to use an old 
(and clearly broken) patch for adding T.38 gateway support to Asterisk 1.8.

You guys know that it works in Asterisk 10, but you say you can't use 
Asterisk 10 for some reason that I don't understand.
