Cisco Unified Videoconferencing 3540 MCU Conference Bridge Configuration for IPVideo Telephony

Note The configuration shown inTable 12-7 directly affects gatekeeper call routing. If MCU Registration

Mode is not set to MCU and instead left at its default setting of Gateway, gatekeeper call routing may

not function in the Very Large Campus Clustering over the WAN deployment model.

Tocreate the Cisco Unified CallManager dedicated H.323 service on the MCU, information was copied

fromthe existing default service prefix 87 named Continuous Presence (MP). The only change made to

this default service prefix was to change the prefix to 25. This prefix must be used when configuring

Cisco UnifiedCallManager route patterns, as described in the “Route Pattern Configuration for MCU

Service” section on page 12-25.
