I'm configuring Mobility Manager 1.2 with CCM 4.3 and H.323. There is also H.323 overlp sending configured.
If I configure the RP to modify the caller id, I hear only MoH on the mobile.
I have configured only mrgls and device pools without moh. So I think the moh is streamed from the phone which is shared with the cti port.
I think it could be a problem with partitions and CSS. I have tried everything, but no luck.
