that govern how coverage is handled.
Instructions
The System-Parameters Call Coverage / Call Forwarding screen sets up the global 
parameters which direct the switch on how to act in certain situations.
1. Leave all default settings as they are set for your system.
2. If you desire to customize your system, carefully read and understand each 
field description before you make any changes.

Creating coverage paths
This section explains how to administer various types of call coverage. In general, 
call coverage refers to what happens to incoming calls. You can administer paths 
to cover all incoming calls, or define paths for certain types of calls, such as calls 
to busy phones. You can define where incoming calls go if they are not answered 
and in what order they reroute to other locations. For example, you can define 
coverage to ring the called phone, then move to a receptionist if the call is not 
answered, and finally access a voice mailbox if the receptionist is not available.
With call coverage, the system redirects a call to alternate answering extensions 
when no one answers at the first extension. An extension can have up to 6 
alternate answering points. The system checks each extension in sequence until 
the call connects. This sequence of alternate extensions is called a coverage path.
The system redirects calls based on certain criteria. For example, you can have a 
call redirect to coverage without ever ringing on the principal set, or after a certain 
number of rings, or when one or all call appearances (lines) are busy. You can set 
coverage differently for internal (inside) and external (outside) calls, and you can 
define coverage individually for different criteria. For example, you can decide 
that external calls to busy phones can use the same coverage as internal calls to 
phones with Do Not Disturb active.
