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.
Sure... The call comes up as PCMU:

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...
