Chapter 5-Cascading Conferences

The connection between the two conferences is created when a dial out IP participant is defined (added) to conference A whose dial out number is the dial-in number of the conference or Entry Queue running on MCU B.

Dialing Directly to a Conference

Dial out IP participant in conference A dials out to the conference running on MCU B entering the number in the format:

[MCU B Prefix/IP address][conference B ID].

For example, if MCU B prefix is 76 and the conference ID is 12345, the dial number is 7612345.

Dialing to an Entry Queue

When dialing to an Entry Queue, the dial out participant dials the MCU B prefix or IP address of MCU B and the Entry Queue ID in the format:

[MCU B Prefix/IP address][EQ B ID].

For example, if MCU B prefix is 76 and the Entry Queue ID is 22558, the dial number is 7622558.

When the participant from conference A connects to the Entry Queue, the system plays to all the participants in Conference A the IVR message requesting the participant to enter the destination conference ID.

At this point, the Conference A organizer or any other participant in the conference can enter the required information for the IVR session using DTMF codes. For example, the meeting organizer enters the destination conference ID - 12345.

Any DTMF input from conference A is forwarded to the Entry Queue on MCU B to complete the IVR session and enable the move of the participant to the destination conference B.

Once the DTMF codes are entered and forwarded to the Entry Queue on MCU B, the IVR session is completed, the participant moved to the destination conference and the connection between the two conferences is established.

Automatic Identification of the Cascading Link

In both dialing methods, the system automatically identifies that the dial in participant is an

MCU and creates a Cascading Link and displays the link icon for the participant ( ). The master-slave relationship is randomly defined by the MCUs during the negotiation process of the connection phase.

Basic Cascading using ISDN Cascaded Link

ISDN connection can be used to link between two MCUs or MCU and gateway and create a cascading conference. Content can be sent across the ISDN Cascading Link.

Network Topologies Enabling H.239 Content Over ISDN Cascaded Links

ISDN Cascaded links that support H.239 Content can be created between two gateways, gateway-to-MCU or between two MCUs in the following network topologies:
