How can I stop Music on Hold (MOH) from playing during MCU hosted conferences?
During a conference if a person puts their phone on hold then everybody in the conference hears it. The workaround has been to simply disable MOH completely (per TAC's recommendation).
This was not a problem when we were only using meet-me-numbers with conferences running on the Subscriber. We're grown so we found an unused 3515 MCU and started running audio-only conferences on it to take advantage of the its DSPs.
We do have the supress MOH during a conference selected in CUCM 6.1
Our technique for conferencing on the 3515 is as follows (per TAC's recommendation).
1. The 3515 MCU registers with a gatekeeper
2. CUCM 6.1 has a route pattern to route select DNs down a gatekeeper control H225 trunk to the gatekeeper.
3. The 3515 MCU has an audio only service running with the appropriate service prefix.
