Cisco Unified Videoconferencing 3540 MCU Conference Bridge Configuration for IP Video Telephony
In addition, these components were tested in the Large Multi-Site Centralized with SRST site model for
EUEM:
• 3544 Cisco Unified Videoconferencing chassis
–
Cisco Unified Videoconferencing 3544 System 60-port MCU module
–
EMP3 board
• 3511 MCU with integrated EMP
The configuration of the 3511 is are similar to the 3540 MCU configuration that this section describes.
Half of the Cisco Unified Videoconferencing-3540-MC10A MCU ports were configured to register as a
SCCP Cisco video conference bridge (Cisco Unified Videoconferencing-35xx) device and were
registered with Cisco Unified CallManager. The remaining ports were deployed as H.323 video
conference resources and registered to the gatekeeper cluster in the MCU zone.
When deployed in a Cisco Unified CallManager SCCP environment, the primary function of the
Cisco Unified Videoconferencing MCU is to provide media processing for conferences. In this capacity,
the Cisco Unified Videoconferencing MCU negotiates parameters with the terminals participating in a
conference, and it provides media processing. Cisco Unified CallManager manages the call flow.
Terminals use Cisco Unified CallManager processes to initiate conferences, and
Cisco Unified CallManager manages the allocation of Cisco Unified Videoconferencing MCU
resources.
When deployed in an H.323 environment, the Cisco Unified Videoconferencing MCU manages its own
resources and provides media processing. Calls are initiated using the processes that the Cisco Unified
Videoconferencing MCU uses for H.323 terminals. In this scenario, you must configure Cisco Unified
CallManager to communicate with an H.323 gatekeeper for inbound calls from the MCU. For outbound
calls, you must configure in Cisco Unified CallManager an H.323 gateway with the MCU IP address as
the device name. This arrangement allows SCCP terminals to participate in conferences that include
other SCCP terminals, H.323 terminals, or terminals of both types.
The following tables show how the Cisco Unified Videoconferencing 3540 MCU was configured using
the Cisco Unified Videoconferencing Administrator web page. Fields not shown in these tables were set
