Huh? G729 sounds very good. Much better than GSM IMO. And at 8k (for the
voice) it's pretty small too. If you can afford it (CPU and license-wise),
G729 is great. If you have the extra bandwidth, then go with G711 of course.
But the OP said:

"posted this to the User list but it might actually be more appropriate
here.  Believe me this is a business question when 128K line costs me
$250/month, and 256K is $500 and so on."

So in this case, using G729 would be quite justified.
