Scheduling Participants and Endpoints
When you schedule conferences, you select the participants you wish to join 
the conference from your endpoint directory. Depending on your system 
configuration, your endpoint directory may be the enterprise LDAP directory 
or the Global Address Book. It may also include Guest Book entries.
For participants that have multiple endpoints registered with the Polycom 
CMA system, the system selects the participant’s default endpoint. You can 
change to another endpoint by selecting it from the Call Info list or by editing 
the participant. 
You can schedule participants without endpoints into conferences. You cannot 
schedule endpoints without owners into conferences. The Polycom CMA 
system can be configured to allow you to overbook dial-in participants. In this 
case, dial-in participants can be scheduled to dial into multiple conferences 
during the same time period, but the system reserves resources for the 
participant for only the first scheduled conference. Dial-out participants 
cannot be scheduled into multiple conferences.
For the same reason, if you schedule participants with endpoints such as 
Polycom CMA Desktop, HDX, VVX, or VSX systems into conference as Dial 
In endpoints, the conference will require external MCU resources.
Bridge Selection and Cascading
When a conference is scheduled with one of the Polycom CMA system 
scheduling applications (Web Scheduler or Scheduling Plug-in for Microsoft 
Outlook or IBM Lotus Notes) and the conference requires external MCU 
resources (such as a Polycom RMX or MGC system), then by default the 
Polycom CMA system automatically assigns the conference to a bridge. 
However, the system allows users with advanced scheduler permissions to 
select a bridge for their conferences. It also allows them to create multibridge, 
cascaded conferences. 
Bridge Selection
When scheduling a conference, users with advanced scheduler permissions 
can select a bridge to host their conference by selecting the Single Bridge 
option. When they select this option, the system presents a list of bridges that 
have the capabilities and resources required to host their conference. 
Because this bridge list depends on the template selection and conference 
settings, users should make their template selection and conference settings 
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.
Bridge Selection and Cascading Conferences
When scheduling a conference, users with advanced scheduler permissions 
can select the Multi Bridge option to create cascading conferences.
