It wouldn't work - Multicast doesn't allow transcoders.

Are you in SRST fallback when you are stating that you are in H323?
Also I assume this is MoH to the PSTN PRI Trunk - since IP phones speak SCCP not MGCP or H323 - am I correct on that assumption?

Anyway - next test you would need to do is to run PerfMon on the (correct) UCM (so most likely MoH server is registered to the Sub CPE if you are using the Sub) and check to see when the music starts - does the MoH PerfMon counter show that the music is coming from the Sub or Pub as either a Multicast or Unicast stream ... if not - you have other things afoot!

Cheers,

Ok, I eliminated the 1st option by only allowing g711. (removed g729 under ip streaming services)

2nd option you mention. How would that happen?

And we know from Mark Snow that the region setting only says 'this is
the MAXIMUM bandwidth' we can use, so if it set to G.711, then G.729
is still available for use.

If you want it to use G.711 for MoH disable G.729 under the IP Voice
Media Streaming App Service Parameter

Or.

Your H.323 destination is forcing G.729 so it is being transcoded...
one of those...
