Re: [OSL | CCIE_Voice] Transcoder and BACD issue
Yes- for calls to the BACD #,unless you use g711 end to end you need a prefix of some kind otherwise the BACD dial-peer will be used the call will fail. (1) Call coming into CME should hit an inbound dial-peer using g729. (2) Prefix should be stripped either using voice translation profile or num-exp (3) Outbound dial-peer should be matched (dial-peer voice 222 voip) (4) transcoder is engaged. The transcoder can only ever be engaged when the codec mismatch is between the inbound and outbound dial-peer (or in a UCM environment when both the endpoints are registered to UCM and a codec mismatch occurs). -- Vik Malhi CCIE #13890 Instructor - IPexpert, Inc.

Again I see no possible way of transcoding this BACD dial-peer configured as documentation states because it acts as both legs of the call and hardcoded to g711u so no way is a transcoder going to be invoked.
