yah so the codec chosen by the inbound leg is always offered in the outbound sdp to try and prevent transcoding. if you set {absolute_codec_string=G722} in the bridge string you will bypass this feature. On Wed, Dec 16, 2009 at 1:41 PM, Kristian Kielhofner < kristian.kielhofner@gmail.com> wrote:

We don't support G729 so this call comes up as PCMU when we answer and then that codec is first in the codec list...
