Speaking for me as a user, MP3 and AAC are at least worthy of 
consideration. Someone said on this list that they waste bandwidth, but 
VoIP's main problem for me as a user is low speech quality, not 
unacceptable traffic. I hear fine voice quality on 128kbps mp3 radio 
streams and really fine on 176kbps ogg; I'd like to have that for phone 
calls.
