Defining Cascading Conferences
Polycom®, Inc. 257
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:

Set the appropriate flags (done once only).
Define the conference setting and its line
rate to be the same as the one set on the
RealPresence Collaboration Server.
Define the conference setting and its line rate to
be the same as the one set on the MGC.
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.
