Firstly you cannot transcode a multicast stream so you are correct there. By placing the MOH server in a g711 Device Pool you are allowing all codecs that take up less bandwidth than g711 too. So that includes g729.
So providing you change the IP Voice Media Streaming service params to allow G729 the MOH stream is being sent to the BR1 natively using g729. -- Vik Malhi CCIE #13890, CCSI #31584 Senior Technical Instructor - IPexpert, Inc.

Now, since BR1phones/BR1 MGCP gw are in a device pool which communicates G729 to other device pools, how would my Multicast MOH get streamed to BR1 phones ? Multicast MOH server is using G711 , BR1 phone is using G729 and since there can be no transcoder invoked for Multicast MOH , how will this work ? Please help !
