Queue Control

The system manager can control the maximum number of calls allowed in the primary calling group queue (not an overflow queue) for calls that arrive on certain facilities often assigned to calling groups. The factory setting is 99, but any value from 0 to 99 can be specified as the maximum. When the number of calls in queue reaches the programmed maximum, subsequent eligible callers receive a busy signal.

Queue control applies to the following types of calls:

For private network trunks, the call returns only when PRI lines are used and the transfer has been manually completed. Calls transferred to a local calling group or using network PRI lines return to the transfer originator.

Dial-in tie trunks, including private tandem tie trunks (Hybrid/PBX mode only) cannot be assigned directly to Calling Groups.

Queue control does not apply to calls received directly on any of the following facilities:

In addition, Remote Access calls to a Calling Group, coverage calls directed to a Calling Group, overflow calls, and outside calls directed to a Calling Group through QCC Position-Busy backup are not eligible for queue control.

When a call is not eligible for queue control, it is added to the Calling Group queue, even if that queue has reached or exceeded the programmed maximum number of calls. The Queue Control setting has no effect. For example, if the maximum number of Calling Group calls is set to 40, and 40 calls have already come in, subsequent callers on eligible facilities hear the busy tone. Calls that arrive on a loop-start line assigned to the Calling Group, however, are added to the queue.
