Revising Allowed Lists
An Allowed List provides some flexibility for extensions with calling restrictions
by allowing specified extensions to dial certain numbers (for example, 911),
regardless of the extension's calling restrictions. Use this procedure to modify
an Allowed List of telephone numbers that can be dialed.
NOTE:
A Disallowed List takes precedence over an Allowed List.
Planning Guidelines
Revising Allowed Lists may affect other features, including Auto Dial, Automatic
Route Selection (ARS), calling restrictions, Conference, Directories, Forward
and Follow Me, Night Service, personal lines, Remote Access, Speed Dial, and
Toll Type. For more information, see the Feature Reference .
NOTE:
When Allowed Lists are used in conjunction with Remote Access to restrict calls
made through the system from remote locations, the Allowed Lists can be
assigned to either a specific barrier code (password) or to specific types of
remote access trunks (for example, all tie/DID trunks).
In Release 3.1 and later systems, star codes may be included in Allowed and
Disallowed Lists. In these releases, dialed star codes are ignored by ARS for
routing calls. Star codes are provided by the central office (CO) to allow the use
of special features (for example, in many areas
feature provided by the central office). In Release 3.0 and earlier systems, the
star code digits were processed as dialed digits by ARS, Allowed Lists,
Disallowed Lists, and calling restrictions. Therefore, the actual called party
number was not properly processed when a star code was entered.
Release 3.1 and later systems permit system managers to include star codes in
Allowed and Disallowed Lists. If a star code is allowed, the digits following the
star code are checked normally by Allowed/Disallowed Lists, calling restrictions,
and ARS.
The MERLIN LEGEND Communications System Release 3.1 and later observes
these Bellcore standards for star codes:
