I beleive leslie is talkign about the other direction - shes not
hearing ringback on calls FROM the PSTN TO the CUCM. the Q.931 setup
messages were inbound.

Leslie, is that correct?

If so, this most likelyhas nothing to do with RTP and is a pure
signaling issue. the only other thing it might be is failure to
provide inband ringback after the call has gone connected and then
been transferred, but now im just making things up.

Leslie, when you say hit/miss from one carrier, are the calls you're
testing all to the same number on the CUCM?
