Reservations

The Reservations option enables users to schedule conferences. These conferences can be
launched immediately or become ongoing, at a specified time on a specified date.
Scheduling a conference reservation requires definition of conference parameters such as
the date and time at which the conference is to start, the participants and the duration of the
conference.
Scheduled conferences (Reservations) can occur once or repeatedly, and the recurrence
pattern can vary.
The maximum number of reservations per Collaboration Server is 2000.

By default, the Scheduler is enabled by a System Flag. The flag prevents potential
scheduling conflicts from occurring as a result of system calls from external scheduling
applications such as ReadiManager®, SE200 CMA™ 4000/5000 and others via the API.
If an external scheduling application is used, the flag INTERNAL_SCHEDULER must
be manually added to the System Configuration and its value must be set to NO.
For more information see "Modifying System Flags" on page 21-1.
In SVC Only conference: up to 60 SVC-based participants
In CP Only conference: up to 20 AVC-based HD participants or 40 AVC-based SD
participants
In a Mixed CP and SVC conference: any combination of SVC and AVC-based
participants depending on the number of AVC and SVC participants.System resources
are calculated according to the Collaboration Server's license. For more information see
"Forcing Video Resource Allocation to CIF Resolution" on page 20-8.
System resource availability is partially checked when reservations are created:
— If a conference duration extension request is received from an ongoing conference,
the request is rejected if it would cause a resource conflict.
— If several reservations are scheduled to be activated at the same time and there are
not enough resources for all participants to be connected:
• The conferences are activated.
• Participants are connected to all the ongoing conferences until all system
resources are used up.
If sufficient resources are not available in the system and a scheduled Reservation cannot
be activated, the Reservation is deleted from the schedule.
