Customizing Extensions
In addition to line assignments, the following procedures can be used to
customize an extension:

Display Language (#303) to specify the language (English, French, or
Spanish) for messages that appear on a system display phone.
Automatic Extension Privacy (#304) to prevent other extensions with
the same line from joining a call at the extension. This feature is also
useful for extensions connected to a modem, fax, or any device whose
function can be disrupted by someone trying to join it.
Forced Account Code Entry (#307) to prevent the extension from
making an outside call until a required account code is entered. You can
also use Forced Account Code List (#409) to create a list of valid
account codes; this ensures that only authorized users with valid account
codes can make outside calls.
Call Waiting (#316) to identify standard phone extensions that can
receive system (not local telephone company) call waiting tone for a
second incoming call when active on a call.
Outgoing Call Restriction (#401) to prevent the extension from making
certain types of outgoing calls (on all system lines).
Disallowed List Assignments (#405) to assign one or more Disallowed
Phone Number Lists to the extension. Use Disallowed Phone Number
Lists (#404) to create the lists of outside numbers that extensions cannot
dial.
Allowed List Assignments (#408) to assign one or more Allowed Phone
Number Lists to the extension. Use Allowed Phone Number Lists (#407)
to create the lists of outside numbers that otherwise-restricted extensions
can dial.
Pickup Group Extensions (#501), Calling Group Extensions (#502),
Night Service Group Extensions (#504), and Hunt Group Extensions
(#505) to place the extension in any of these groups. See “Setting Up
Groups of Extensions” later in this chapter for more information.
Fax Machine Extensions (#601), Doorphone Extension (#604 and
#605), Doorphone Alert Extensions (#606), or AA Extensions (#607),
External Hotline (#311), or Hotline (#603) to identify the extension as
one of these equipment types.
“Setting Up Auxiliary Equipment” later in this chapter provides an
overview of the procedures you use for setting up devices, such as
voice messaging systems and call reporting devices. Also, Chapter 4
provides detailed information and example applications for auxiliary
equipment.
