Feature Reference
Description
Coverage allows a call ringing at one extension (a sender ) to ring at another
extension (a receiver ) at the same time, and to be answered at either extension.
It is not necessary for the sender and receiver to have shared personal lines or
Shared SA buttons. A coverage sender, the extension whose calls are covered,
can be an individual extension ( Individual Coverage ) or a group of extensions
( Group Coverage ).
An extension becomes a sender and has its calls covered in either or both of
the following ways:
An Individual Cover button is programmed for the sender on a multiline
telephone (a receiver).
The sender is made a part of a coverage group through system
programming. A receiver for the group is programmed in any of the
following ways:
A Group Cover button is programmed for the group on a multiline
telephone (a receiver).
The Queued Call Console (QCC) queue is programmed to be a
receiver for the group.
A calling group is programmed to be a receiver for the group.
An individual multiline telephone can have any combination of up to eight
Individual Cover and Group Cover buttons.
Several timers, summarized in Table 4, affect the delivery of a call to coverage.
Explanations of these timers are included in the descriptions of Individual
Coverage and Group Coverage later in this section.
Individual Coverage
An Individual Coverage receiver, who covers calls, has a button programmed
on his or her multiline telephone that corresponds to another extension. A given
sender can have up to eight Individual Coverage receivers covering calls. A
receiver can have separate buttons for up to eight senders, but can have only
one button to provide Individual Coverage for a given sender.
A button for Individual Coverage can be programmed as either Primary Cover or
Secondary Cover. The Secondary option provides a 2-ring delay (the Secondary
Coverage delay interval) to allow the sender to answer before the receiver; the
Primary option does not provide this delay. In addition, each Cover button can
be programmed with ringing options: Immediate Ring, Delay Ring, or No Ring.
