Description
Used in conjunction with calling restrictions (outward and toll), an Allowed List is
a list of numbers that the caller is allowed to dial, despite restrictions. For
example, an Allowed List assigned to an outward-restricted extension can allow
calls to specific local numbers, such as emergency (911) or toll numbers. For
toll-restricted extensions, an assigned Allowed List can allow calls to specific
area codes and/or exchanges needed for daily tasks.
A Disallowed List is a list of local or toll numbers that the telephone user is not
allowed to dial, even if the extension is otherwise unrestricted. Disallowed Lists
can be used as an alternative to or in conjunction with calling restrictions.
Both Allowed Lists and Disallowed Lists are assigned to individual extensions.
Allowed and Disallowed Lists can also be used in conjunction with Remote
Access to restrict calls made through the system from remote locations. In this
case, Allowed and Disallowed Lists can be assigned to either specific remote
access barrier codes or (if barrier codes are not used) to specific types of
trunks (all tie/DID and all non-tie/non-DID trunks).
When an Allowed List is assigned to a barrier code or remote access trunks, the
remote access user using that code can dial specific numbers included in the
list. When a Disallowed List is assigned to a barrier code, the remote access
user using that code cannot reach the specific numbers included in the list.
If barrier codes are not used for remote access, then Allowed and Disallowed
Lists for remote access users can be assigned to all tie/DID trunks and all
non-tie/non-DID trunks.
A Night Service Allowed List can be programmed with up to 10 numbers that
anyone can dial without having to enter a Night Service password. For
additional information, see "Night Service."
