Cisco Unified CallManager Configuration for IP Video Telephony
Route Pattern Configuration for MCU Service
Cisco Unified CallManager routes outbound calls to the MCU via this H.323 gateway utilizing a route
pattern. In Very Large Campus Clustering over the WAN deployment model this route pattern was
21XXX.
Note The route pattern must begin with the same digits as the service prefix configured on the Cisco Unified
Videoconferencing 3540 MCU.
Cisco Unified Videoconferencing PSTN Gateway Configuration for
Cisco Unified CallManager
These sections describe how the PSTN gateway was configured for Cisco Unified Videoconferencing:
• Video PSTN Gateway, page 12-25
• Route Pattern Configuration for Cisco Unified Videoconferencing PSTN Gateways, page 12-26
Video PSTN Gateway
A Cisco Unified Videoconferencing gateway registers as a gateway on Cisco Unified CallManager, and
it uses a specific signaling port. Table 12-29 lists the signaling port for each type of MCU and gateway.
Note If you want to use the 1720 standard value for the signaling port on Cisco Call Manager configuration,
you can change this value for Cisco Unified Videoconferencing devices.
