Defining Cascading Conferences

Cascading via Entry Queue

The link between the two conferences is created when a participant that is defined as a dial-out cascaded link in one conference (Conference A) connects to the second conference (Conference B) via a special cascaded Entry Queue (EQ). When MCU A dials out to the cascaded link to connect it to conference A, it actually dials out to the cascaded Entry Queue defined on MCU B.

Cascaded Conferences - Star Topology

Though the process of cascading conferences mentioned in this section refers to conferences running on two different RealPresence Collaboration Server units, it is possible to cascade conferences running between RealPresence Collaboration Server units and other MCUs.

The following features are not supported by the cascaded link and therefore are not supported in the combined conference:

●DTMF codes are enabled in cascaded conference, but only in their local conference. The operations executed via DTMF codes are not forwarded between linked conferences.

●FECC (Far End Camera Control will only apply to conferences running in their local MCU).

Enabling Cascading

Cascading two conferences requires that the following procedures are implemented:

●Creating the cascade-enabled Entry Queue

A cascade-enabled Entry Queue must be created in the MCU hosting the destination conference (Conference B). The cascade-enabled Entry Queue is used to establish the dial-in link between the destination conference and the linked conference and bypassing standard Entry Queue, IVR prompt and video slide display.

●Creating a cascade-enabled Dial-out link

The creation of a cascade-enabled dial-out link (participant) in the linked conference (Conference A). This dial-out participant functions as the link between the two conferences.

●(Optional) Enabling the cascaded linked participant to connect to the linked conference (Conference A) without entering the conference password. This can be done by modifying the default settings of the relevant system flag.
