Calling Group Options

This section contains instructions for following calling group options:
Hunt Type

Message-Waiting Receiver
Calls-in-Queue Alarm Threshold
External Alert for Calls-in-Queue Alarm
Overflow Coverage
Overflow Threshold
Overflow Threshold Time
Group Type
Only one announcement device can be designated for each calling group;
however, more than one calling group can use the same announcement device.
The announcement device should not be assigned as a group member, and it
must be outward-restricted to prevent unauthorized calls.
Each calling group can have only one telephone assigned as its message-
waiting receiver. The same telephone can be assigned as the message-waiting
receiver for more than one calling group.
The external alert designated as a calls-in-queue alarm can be any alerting
device connected through an MFM in the External Alert mode for MLX
telephones. Only one external alert can be designated for each calling group.
Since the signal is continuous, you should only use lighted external alerting
devices. An alert connected to a Supplemental Alert Adapter for an analog
multiline telephone should not be used as a calls-in-queue alarm.
The Overflow Threshold determines the maximum number of calls waiting in the
calling group queue before being sent to the Overflow receiver. The Overflow
Threshold Time determines the maximum amount of time that any call waits in
the queue before being sent to the Overflow receiver. The Overflow Threshold
should be set to a number larger than the Calls-in-Queue Alarm Threshold to
ensure that the Calls-in-Queue Alarm will alert before calls are sent to the
Overflow receiver. If the Overflow Threshold Time is the primary source for
overflow, set the Overflow Threshold to a large number of calls (for example, 99
calls). If you want calls to overflow based on the number of calls in the queue,
disable the Overflow Threshold Time by setting it to 0 seconds.
