Receiver Allocation Control; Busy Recordings - Mitel SX-200 Practices

Functional Description
hour and 100/l 80 or at least one receiver is needed to service all of the callers in that
hour. Round the result of this calculation up to the next whole number.
Note: The minimum quantity of receivers must be equal to the number of RADs assigned to the
Automated Attendant feature so that RADs can operate concurrently.
Receiver Allocation Control
The user can place limits on the number of receivers available to the Automated
Attendant feature (across all Auto-Attendant groups). Without this limit, the Automated
Attendant feature can potentially use up all receivers in the system and block dialing
for extended periods.
,
The limit is specified by programming System Option 59, Receivers Reserved for
Non-AutwAttendant Use. The Automated Attendant feature uses as many receivers
as possible but will always leave at least this number of receivers available for the rest
of the system.
Receivers going out of service (for diagnostics, etc.) have no effect on this number.
Reducing the number of available receivers impacts the Automated Attendant feature
first.
When the limit is specified, the system does not check to ensure that the number of
receivers present in the system is greater than the number of receivers programmed
as a limit. If the system contains fewer receivers than the limit, the Automated Attendant
feature is unable to access any receivers. The system handles this as a "no receivers
available" condition.
Setting the number of receivers to more than the number in the system results in all calls
that are directed at Auto-Attendant groups ending up at the default destination.
Busy Recordings
If a call arrives at the Automated Attendant when all recordings are busy or unavailable,
the caller is camped on to the group to wait for a recording. The wait time is
programmable for each group through CDE. Unless all of the RADs fail, the caller wait
time should be no longer than the RAD cycle time. Normal camp-on audio is returned
to callers.
When a recording becomes free, the system rings the RAD. When the RAD answers,
the system sets up a listen only conference for all callers camped on to the
Auto-Attendant group. The callers are retrieved using the normal
camp-on priority scheme. Callers will be retrieved until either there are no more waiting
callers or all available DTMF receivers in the system have been allocated. (DTMF
receiver allocation is subject to the receiver usage limits for the Automated Attendant
feature in the system.) Once all receivers are used up, the remaining callers continue
to wait for resources to become free.
