Defining Cascading Conferences

●When creating a cascading link between two MGCs the MGCs must be configured to operate in VSW mode.

For more details about the MGC to MGC connection, see the MGC Manager User’s Guide, Volume II, Chapter 1, Ad Hoc Auto Cascading and Cascading Links.

●To enable the connection of the links between cascaded conferences, they must run at the same line rate.

●To enable Content sharing between the RMX and the MGC, the rate allocated to the content must be identical in both conferences. Make sure that the line rate set for both conferences, and the Content Settings (Graphics, Hi-res Graphics or Live video) are selected correctly to ensure the compatible rate allocation. For more details on the RMX rate allocation to the Content channel, see SIP BFCP Content Capabilities.

The following table summarizes Video Session Modes line rate options that need to be selected for each conference in the cascading hierarchy according to the cascading topology:
