Chapter 5-Cascading Conferences

Polycom, Inc.

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 the IVR session is completed, the participant is 

connected to the conference and the connection between the conferences is established. The 

system automatically identifies the calling participant as an MCU and the connection is 

identified as a cascading link and the cascading link icon is displayed for the participant 

(

).

To enable Gateway-to-Gateway, Gateway-to-MCU and MCU-to-MCU calls over ISDN 

Cascading links, the following configurations are required:
•

Modifying the IP Network Service to include the MCU Prefix in the Gatekeeper (in the 

Gatekeepers dialog box). For more details, see "Modifying the Default IP Network Service” 

.

•

ISDN Network Service is configured in both MCUs. For more details, "Modifying an

•

Configuring a Gateway Profile and assigning dial-in ISDN/PSTN numbers. For details,

•

Configure the Entry Queue or conference (for direct dial-in) is enabled for ISDN 

connection and a dial-in number is assigned (for example 54145106). 

•

Defining the dial-in ISDN participant in MCU B and Dial-out ISDN participant in MCU 

A (for MCU-to-MCU cascading conferences).
