Group Calling
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.
If you want the Overflow Threshold Time setting to be the primary source for
overflow, you should specify an Overflow Threshold setting of a large number of
calls (for example, 99 calls). If you want to have overflow by number of calls in the
queue, set the overflow threshold time to 0 seconds; this turns off overflow by
time.
Overflow Receiver
When the number of calls waiting in the calling group queue reaches the overflow
threshold, calls can be sent to an overflow receiver, which can be another calling
group or the Queued Call Console (QCC) queue. Only one calling group or the
QCC queue can be programmed to provide overflow coverage for the same
calling group, and each calling group or the QCC queue can provide overflow
coverage for more than one calling group. If no overflow receiver is programmed,
the call continues to ring in the queue until it is answered or the caller hangs up.
Calling Group Overflow Receiver
Calls to do not go to an overflow receiver that is a calling group until each of the
following conditions is met:
The number of calls in the queue is equal to or greater than the
programmed overflow threshold or the time a call has been in the queue is
over the overflow threshold time.
The overflow calling group has an available calling group member.
No other calls are already queued for the overflow calling group.
If all conditions are met, the calls are directed to the overflow receiver on a
first-in/first-out basis until the number of queued calls in the covered calling group
is less than the overflow threshold. The system searches for an available calling
group member according to the hunt type assigned to the sending calling group.
Calls that overflow to a secondary group cannot overflow again or hear a second
announcement.
When the overflow group type is set to Auto Logout and an overflow call is not
answered within 30 seconds (5 rings), the overflow calling group member is
logged out. The call is returned to the sender calling group's queue and is placed
at the front of the queue. The caller does not hear the sender's delay
announcement even if the call was sent to the overflow calling group before the
caller heard the delay announcement.
