We have three servers confdigures as MOH servers, one has mulitcast enabled, the other two do not.
Our branches have voice gateways, and all phones in remote branches are in the same MRGL, (configured in each device pool).
The MRGL holds a MRG that has two servers in it, the first server is unicast, the other is multicast, but the "Use Multi-cast Audio (if at least one multi-cast MOH resource is available"
This would mean I am not using mulicast at all if this is not checked correct?
Does the Selected Media Resource go in priority, top down?
If I am using unicast, is the MOH sent as an RTP stream to the on hold party?
