CME by default doesn't actually only advertise g729. If you match an
incoming voip dial peer, and under that incoming dial peer you haven't set a
codec it will be g729.
If however, you do not match an inbound voip dial peer, you will match dial
peer 0 which will actually advertise almost every codec possible.
Just a little note, hopefully you're matching an non-0 dial peer.
