Coverage
Considerations and Constraints
In Release 2.0 and later systems, if a receiver calls a sender for whom he or she
is covering and the sender is busy or unavailable, the call proceeds to other points
of coverage. It does not come back to the receiver who originated the call. In
Release 1.0 and 1.1 systems, a call from a receiver to a sender is not covered.
A maximum of eight Primary Cover and Secondary Cover buttons can be
assigned to provide Individual Coverage for a given sender. Only one Cover
button for each sender can be programmed on a multiline telephone.
A maximum of eight Group Cover buttons can be assigned to provide Group
Coverage for each coverage group. All eight can be programmed on one multiline
telephone, or the Group Cover buttons can be distributed on as many as eight
multiline telephones.
A receiver with a multiline telephone can have as many as eight Cover buttons,
which can be programmed for any combination of Group and Individual Coverage.
If a receiver has both a Primary Cover or Secondary Cover button for a sender
and a Group Cover button for the group of which the sender is a member, a call
for the sender rings only at the receiver's Primary Cover or Secondary Cover
button. This prevents multiple deliveries of the same call to the same receiver.
Each coverage group can have any number of members, from none to all the
extensions in the system.
Each sender can be a member of only one coverage group.
If a sender without Individual Coverage is a member of a coverage group and no
receivers are assigned for the group, a caller hears ringback instead of a busy
tone when the sender is unavailable.
If a calling group is assigned as a receiver for a coverage group, it is the only
receiver for that group; no other types of Group Coverage receivers can be
programmed. However, individual members of the coverage group can be
senders to Individual Coverage receivers.
A calling group can be a receiver for up to 30 coverage groups.
A receiver with a Group Cover button can also be a member of the coverage
group for which the button is programmed. Calls to that receiver are sent to all
other receivers programmed for the group.
When both the QCC queue and multiline telephones are programmed as
receivers for a coverage group, the QCC queue is not counted in the 8-receiver
maximum for the group.
A QCC cannot be a coverage sender.
