port reservations are only permitted when the MCU can guarantee them for
repetition of a conference. As an
example, a conference scheduled to run from 08:00 to 10:00 on the second Monday of each month will be deemed to
clash with a conference configured to run from 09:00 to 09:30 every Monday, even though the former will only really
clash with the latter every fourth or fifth week.

In general, to make best use of the available MCU media ports, conferences should not be scheduled for longer than
they are needed, and repetitions should be limited, either by end date or number, wherever possible.

Because port reservations are mandatory in
every active conference must have configured values for
the number of video ports and the number of audio-only ports to reserve for it. In turn this means that every active
conference must be configured, and therefore ad hoc conferences are not permitted when in

If a participant calls in to the MCU and connects to an auto attendant, the MCU does not know which conference

, the auto attendant connection allocates a media port from those not currently in use. If all of
the media ports are in use, the endpoint's connection will be dropped by the MCU.
, the auto attendant connection effectively "borrows" a media port from those not currently in use.
However, this borrowed media port has a lower priority than a media port used by a conference participant, and if
the auto attendant connection "borrows" the last remaining media port, then that connection will be dropped if
another endpoint connects directly to a conference and requires a reserved media port.

In general, changing port reservation mode when there are active connections is not recommended. The effects of
changing mode include, but are not necessarily limited to:

Participants in a scheduled conference may be disconnected. For each conference, the maximum port usage
values (for unreserved mode) and the ports to reserve (for reserved mode) are configured and stored
separately. Therefore when changing port reservation mode, it is possible that there are more active
participants than allowed in the particular mode. In this case, participants are disconnected to reduce the
number to that allowed.
