■ If the number of waiting calls is greater than or equal to the Threshold 2
value but fewer than the value for Threshold 3, the LED winks.
■ If the number of waiting calls is greater than or equal to the highest value,
Threshold 3, the LED lights steadily.
An external alert only signals when the number of calls in the queue is greater
than or equal to the programmed Threshold 3 value.
These thresholds can be used to assess the effectiveness of delay
announcements. See “Using Alarm Thresholds to Monitor the Effectiveness of
Delay Announcements” on page 329 for details.
NOTE:
In Release 6.0 and later systems (Hybrid/PBX mode only), a Calls-in-Queue
Alarm button or alert must be connected to an extension on the same
system as the calling group for which it reports.
Overflow Threshold
The overflow threshold is the maximum number of calls waiting in the calling
group queue before calls are sent to the overflow receiver. The factory setting is
one call.
The Overflow Threshold option should be set to a number larger than the
Calls-in-Queue Alarm Threshold so that the Calls-in-Queue Alarm alerts before
calls are sent to the overflow receiver. In Release 5.0 and later systems, the
overflow threshold should be greater than the highest Calls-in-Queue alarm
threshold (Threshold 3).
The Overflow Threshold option can be used in conjunction with the Overflow Time
and Prompt-Based Overflow (Release 6.0 and later systems) options described in
the next two sections. Overflow distribution based on the number of calls in the
queue or the time spent in the queue takes precedence over calls that go to
overflow because of the caller’s prompt.
Overflow Threshold Time
In Release 4.0 and later systems, there is also an Overflow Threshold Time
setting. The overflow threshold time is the maximum time that any call can remain
in the calling group queue before it is sent to the overflow receiver. If the overflow
threshold time is set to 0 seconds (factory setting), then the Overflow by Time
option is off. If the overflow threshold time is set to any other valid interval (1–900
seconds), then calls that remain in the calling group queue for a time equal to or
greater than the overflow threshold time are sent to the overflow receiver.
