Polycom® CMA™ System Overview
Polycom, Inc. 3
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 CascadingWhen 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.
