i think you've got that backwards. 80 kbit/sec on the wire is not a
lot these days, and in a world where we're conditioned to accept gsm
or worse, un-transcoded g.711u sounds startlingly good. if you're so
short on bandwidth that moving to a 24 kbit/sec on the wire codec
makes a difference, you're on the ragged edge of being hosed.
