2-22 Allowed Lists
Assigned to individual telephones via system programming, an Allowed List is a
list of telephone numbers that a user with an outward- or toll-restricted telephone
can dial.
For example, an Allowed List assigned to an outward-restricted telephone can
permit calls to specific local or toll numbers, such as emergency numbers (911).
For toll-restricted telephones, an assigned Allowed List can allow calls to
specific area codes and/or exchanges needed for daily tasks.
A maximum of eight lists can be programmed, and each list can contain a
maximum of ten numbers.
More than one Allowed List can be assigned to each telephone up to the
maximum of eight.
Individual Allowed Lists are numbered 0 through 7, and within each list,
entries are numbered 0 through 9.
Each number in a list can have a maximum of six digits (for example, an area
code followed by an exchange) plus a leading 1 if a toll prefix is required.
Special characters, such as Pause, cannot be used in Allowed list entries.
A user with an outward-restricted telephone cannot dial an outside number by
using an Auto Dial button unless the number is on an Allowed List assigned to
the telephone. A user with a toll-restricted telephone cannot dial a toll number
by using an Auto Dial button unless the number is included on an Allowed List
assigned to the telephone.
ARS checks calling restrictions before choosing the route for a call. This
prevents users with restricted telephones from dialing numbers that are not
included on an Allowed list.
When used with calling restrictions, Allowed Lists can permit the dialing of
specific numbers such as emergency numbers from an outward- or toll-
restricted telephone.
