The only configuration on UCCX related to MoH is the Audio Source selected on the CTI Port for the User Hold Audio Source and the Network Hold Audio source. Each time the UCCX script puts the call on hold, the audio stream gets connected to the MoH source on the CUCM or MoH server. UCCX doesn't control what MoH is played to the caller though beyond the device configuration when the CTI ports are being created.
I believe a fixed MoH Source would address this. Just as a heads up, The multicast option for MoH is not a supported feature with CTI devices like UCCX ports, as it can lead to transfer issues in some cases.
Here's a thread I came across on the IPT forum that discusses MoH restarting each time a call is put on hold.
There'ss a common misconception about CTI ports and mcast MoH.. the CTI ports don't support reception of mcast MOH, but then, UCCX isn't interested in listening to MoH anyway... so it makes sense so assign no MoH resource at all to the UCCX CTI Ports' MRGL.
You can assign an mcast MoH MRGL to the gateways and phones that are calling UCCX, and they can pick it up just fine.
The CTI Port configs identify which audio source should be played, and the MRGL of the far-end device controls where that audio comes from.
So you can mcast enable the MoH which causes it to play continuously rather than restart... assuming your gateways are reachable from the CCM via multicast.
