Page 40Allowed/Disallowed Lists
Individual Allowed and Disallowed Lists are numbered 0 through 7. Within each
list, there are 10 entries, numbered 0 through 9.
The Pause character (entered by pressing the Hold button) can be used as a wild
card character in Disallowed Lists, for example, to indicate that calls to a given
exchange are restricted in every area code. The Pause character is shown on the
planning form as p. Wild card characters are not permitted in Allowed List entries.
The Pause character does not act as a wild card for the
character.
When used in conjunction with Remote Access, Allowed and Disallowed Lists are
assigned to specific barrier codes or to types of lines/trunks: all tie/DID trunks, or
all non-tie/DID trunks. Allowed and Disallowed Lists cannot be assigned to trunks
on an individual basis.
When used with Automatic Route Selection (ARS), Allowed and Disallowed Lists
are not applied until the caller dials the ARS code and a pool is selected.
Because restrictions imposed by a Disallowed List apply to the extension used to
initiate a call to an outside number, a user with a restricted extension can
circumvent restrictions by asking an operator with an unrestricted console to
connect an outside call.
Feature Interactions 0
Auto Dial A user with a restricted extension cannot dial a restricted number (outside
or toll) by using an Auto Dial button unless the number is on the Allowed
List for that extension. A user cannot dial an outside number by using an
Auto Dial button if the number is on a Disallowed List.
Automatic Route
Selection
ARS checks Allowed and Disallowed Lists before choosing the route for a
call. This prevents users with restricted extensions from dialing numbers
that are not on an Allowed List. ARS also prevents a user from dialing
numbers on a Disallowed List.
Calling Restrictions When used with calling restrictions, Allowed Lists can permit the dialing of
specific numbers, such as emergency numbers, from an outward- or
toll-restricted extension.
Conference A user with a restricted extension cannot add a participant (outside or toll)
to a conference call unless the participant’s number is on the Allowed List
for that extension.
A user cannot add an outside number to a conference call if the number is
on a Disallowed List.
Directories A user with a restricted extension cannot use the System Directory to dial
a restricted number unless the System Speed Dial number is marked, or
the number is on the Allowed List for that extension.
