Defining Cascading Conferences

MGC to RealPresence Collaboration Server Cascading

If MGC is running version 9.0.4, and RealPresence Collaboration Server is running version 7.0.2 and higher, the RealPresence Collaboration Server can be set as Master on level 1 and MGC as Slave on level 2.

MGC running versions other than 9.0.4 is always on level 1 and must be set as the Master MCU.

If the cascading topology includes additional MGCs as well as RealPresence Collaboration Servers it is recommended to define Video Switching conferences for all the cascading conferences running on the MGC in the topology.

Two methods can be used to create the Cascading links between conferences running on the RealPresence Collaboration Server and MGC:

●Method I - Establish the links by defining a dial-in and a dial-out participant in the Slave and Master conference (where the Master conference is created on the MCU on Level 1 and the Slave conference is created on the MCU on Level 2).

●Method II - Using a Cascading Entry Queue on either the MGC or the RealPresence Collaboration Server depending on the dialing direction and the MCU Level. This is recommended when the RealPresence Collaboration Server is on Level 1.

Method I

Depending on the dialing direction, the following procedures must be performed:

RealPresence Collaboration Server.

Define the dial-in participant (Cascaded Link) with the calling number from the MGC.

The alias that will be used to identify the dial-in participant can be the name of the calling slave conference.

Set the Cascading option as Master.

Define the dial-out participant (Cascaded Link) to the conference running on the RealPresence Collaboration Server. Set the dial-out alias to be the prefix of the MCU and the name of the master conference running on the RealPresence Collaboration Server.
