Hi Rich,

Thanks for writing back to me.  Yep, just like you, I too am looking for a
lower bandwidth codec for my outbound.  And, yes, broadvoice only officially
supports G.711.  That being said, is there even a way to do this scenario in
asterisk?

Thanks,
       - Andre

Unless broadvoice changed something, they only officially support g711
(not g729). So, config your system to only allow ulaw and dtmf=inband
for broadvoice.

The g711 requirement is why I gave up and discontinued their service
since I have limited dsl bandwidth on my end.
