[Freeswitch-users] Proxy Media and Codec Prefer

[Steven Ayre]

In proxy media mode FS will pass media straight through without any
processing. It won't do any transcoding or any SDP modifcation, so it can't
transcode PCMU <-> G729 and absolute_codec_string will be ignored - it'll
just pass the codec settings straight through from the A leg to the B leg.

So it's expected behaviour.
