Because this bridge list depends on the template selection, users should make 

their template selection before selecting a bridge. Otherwise, they may select a 

bridge that cannot meet their conferencing requirements. In this case, the 

conference will fail to schedule.

When scheduling a conference, users with the Advanced Scheduler role can 

select the Multi Bridge option to create cascading conferences. 
In some respects, a cascaded conference looks like a single conference, but it is 

actually two or more conferences on different bridges that are linked together. 

The link is created by a dial-out from one conference to a second conference 

via a special cascaded entry queue. 
Some reasons you may wish to create cascading conferences include:
• To invite more conference participants than any single bridge can host
• To connect different bridges at different sites into a single conference
• To use the different capabilities of different bridges (for example, different 

communication protocols, such as, serial connections, ISDN, etc.) 

When you create a multibridge, cascaded conference, you must manually 

select bridges and create the cascaded links between bridges by identifying the 

originating bridge, the terminating bridge, and the network type (IP or ISDN). 

The system displays an interconnection diagram that illustrates the cascaded 

links. Once scheduled, each cascaded link appears as a participant in the 

conference. 
By default, the system automatically assigns participants to the “best bridge” 

for them based on available capacity, location, and least cost routing rules. 

However, you may also choose to manually assign participants to bridges.

When a conference is scheduled with one of the CMA system scheduling 

applications (Web Scheduler or Scheduling Plug-in for Microsoft Outlook or 

IBM Lotus Notes), by default the system automatically assigns the conference 

to a bridge unless a user with the default Advanced Scheduler role intercedes. 

If that bridge is down at the time the system starts the conference, the CMA 

system attempts to dynamically reassign the conference to another bridge with 

sufficient capabilities and resources. 
• If the system can successfully reassign the conference to another bridge, 

the conference starts on the newly selected bridge, and the system sends 

an updated conference email to all scheduled participants. This updated 

email includes a new dial-in number that dial-in participants must use to 

join the conference. 

• If the system cannot successfully reassign the conference to another 

bridge, the conference fails to start. The system sends an email to notify the 

conference organizer of the failure.
