Planning Form Instructions

Check "No" if youdo not want an external alert for Calls-in-Queue Alarm
and continue to the "Overflow Coverage" instructions.

In the "Adjuncts" section, under "Alert Device":
2 . Check the box that indicates the alert is used as a Calls-in-Queue Alarm.
3 . Write the calling group extension number in the space provided.
You can provide backup coverage for a calling group by designating another
calling group to receive calls when the number of calls waiting in the queue
reaches a certain level.
A calling group can provide overflow coverage for more than one calling group;
however, group members cannot tell which group's calls they are answering. In
addition, callers do not hear the overflow group's delay announcement.
If you assign an overflow group, choose the threshold (the number of calls to
wait in queue before they are sent to the overflow group). The factory setting
is 1. You can change the setting to up to 99 calls.
