You may, however, live in a region where for calls within your own area code,
you must dial 10 digits (that is, the area code and telephone number). If this
applies to you, enter 000 for the home area code and enter your area code
as a local area code. After setting, if you receive a call from within your area
code, the screen displays the 10 digits of the telephone number.
For details, see the AREA CODES section (page 42 of the installation guide).
Line group: A group of system telephones sharing some lines within a multi-
telephone system.
Local area code: Most users dial 11 digits to make calls outside their home
area codes. If this applies to you, you do not need to program any local area
codes.
However, if you dial only 10 digits to make calls to some areas outside your
home area code (without dialing 1), then set these local area codes on the
telephone. Up to five local area codes can be set. For details, see the
AREA
CODES section on page 42 of the installation guide. After setting, if you
receive a call from one of these local area codes, the screen displays the 10
digits of the telephone number.
Mailbox: A place to store answering system messages. A 1080 phone can
store system extension messages for your extension.

battery, all programming and messages are retained.

phone and for scrolling through feature options (
[ENTER], [ ], [ ], [ ], [ ]).
Prime line: This is the line on the telephone you assign to be selected
automatically when you lift the handset, press
[ SPEAKER] or press
[HEADSET] to answer or make a call.
System extension message: The messages recorded for individual 1070 and
1040 telephones that are associated with a 1080 phone’s auto attendant mailbox
(page 59).

system (also called an extension).
