Yeah, but that was painful, wasn't it? ;)

So you won't win much from doing compression on iax2. 

Nevertheless, there isn't much point in arguing. Asterisk people will 
continue working/improving IAX and the people in the carrier world will 
continue ignoring it (and/or laughing at it). Frankly, until IAX 
scalability issues are resolved and a large media gateway manufacturer 
commits to supporting it (heh!) I don't see this changing.
