Once a receiver answers a call received on a personal line on a Cover button
and puts the call on hold, the sender and any other user who shares the
personal line cannot pickup the call by pressing the Personal line button. For
proper handling, the receiver should transfer the call to the sender.
An Individual or Group Coverage sender or receiver can be a member of a
pickup group. This allows Pickup to be used to answer a ringing Individual or
Group Coverage call. If a sender who is a member of a Pickup group uses
Coverage On/Off to prevent calls from being sent to individual or Group
Coverage receivers, his or her calls can be picked up by using the Individual
Pickup feature. However, calls cannot be picked up by using the Group Pickup
feature. When a Coverage call is answered by using Pickup, the call
appearance is removed from all other telephones in the Coverage arrangement.
Calls received on a sender's pool button programmed for immediate or delayed
ring are eligible for Individual or Group Coverage.
An individual QCC cannot be a sender or receiver for Individual or Group
Coverage, but the QCC queue can be assigned as a receiver for 1-30 coverage
groups by assigning one or more QCC system operators to receive the calls.
The QCC queue can be assigned as a receiver in addition to multiline
telephones programmed with Group Cover buttons; however, the QCC queue is
not counted in the eight-receiver maximum for each coverage group. The QCC
queue priority and the individual system operator that receive calls for each
coverage group are independently assigned for each group.
When the QCC queue is programmed as a receiver for a coverage group and a
personal line on a coverage group member's telephone is also programmed to
ring into the QCC queue, calls received on that personal line are not sent to the
QCC queue as coverage calls. However, calls received on the personal line can
be sent to multiline telephone Group Coverage receivers.
If Group Cover buttons are programmed for a coverage group in addition to the
QCC queue and all QCC system operators are in Position Busy mode, a Group
Coverage call does not go to a backup calling group.
When the QCC queue is programmed as a receiver for a coverage group and a
call transferred to a group member is not answered, the call is returned to the
queue as a transfer return if the QCC Return Ring Interval is shorter than the
Coverage Delay Interval. If the QCC Return Ring Interval is longer than the
Coverage Delay Interval, the call returns to the QCC queue as a Group
Coverage call.
Reminder Service calls are not eligible for Individual or Group Coverage.
