Features
Coverage
One of the system's unique capabilities is the variety of automatic coverage
possibilities. The features we describe as coverage allow a call ringing at one
extension (a sender ) to also ring at another extension (a receiver ). Here are the
types of senders we refer to:
An individual at an extension (Individual Coverage)
A group called a coverage group (Group Coverage)
A variety of different receivers can be assigned to take calls for an individual or
a coverage group:
Another individual
A calling group
A voice mail system
An operator
Unless the receiver is a Queued Call Console (QCC) operator or a calling
group, his or her phone is assigned Cover buttons; each should be labeled with
the name of the group or individual they are covering for (for example, Cover
Sales or Cover Juan ). Covered calls come in on these buttons, so the receiver
knows whose call he or she is answering.
Depending upon the needs of the business, a sender can have immediate
coverage (called Primary Coverage ) or delayed coverage (called Secondary
Coverage ), where the call rings at the sender's phone and only goes to the
receiver's phone when the sender doesn't answer.
The ringing for covered calls depends upon whether Primary (immediate) or
Secondary (delayed) Coverage is provided. System programming determines
settings for these timers, and calls that are covered by calling groups or
operators may be further delayed as they for someone to answer.
Coverage senders can use programmed buttons on their phones to turn voice
mail coverage on or off, coverage of inside calls on or off, or all Individual
Coverage on or off. Table 4–9 summarizes these options.
