Toll Restriction
• Description
Toll Restriction limits the numbers an extension user may dial. By allowing extensions
to place only certain types of calls, you can better control long distance costs. The
system applies Toll Restriction according to an extension’s Toll Restriction Class. The
system allows for up to 15 Toll Restriction Classes.
Toll Restriction offers the following capabilities:
•
Common Permit Code Table
Use the Common Permit Code Table when you have numbers you want all
Toll Restriction Classes to dial. To let all users dial 000 (000 is an emer-
gency call in Australia), for example, put 000 in the Common Permit Code
Table. The Common Permit Code Table overrides the Restrict Code and
Common Restrict Code Tables. The system provides 10 tables, with 10
entries in each table. Each code is 4 digits max., using 0-9, #, * and FLASH
(as a wild card).
•
Common Restrict Code Table
The Common Restrict Code Table lets you globally restrict certain numbers
for all Toll Restriction Classes. To prevent all users from Dialling directory
assistance (411), for example, put 411 in the Common Restrict Code Table.
Be sure you don’t allow the codes you want to restrict in the Permit Code
Table or the Common Permit Code Table. The system provides 10 tables,
with 10 entries in each table. Each code is 4 digits max., using 0-9, #, * and
FLASH (as a wild card).
•
Restrict Code Table
When you want Toll Restriction to allow most calls and restrict only selected
calls, use the Restrict Code Table. To block only 1-900 calls, for example,
enter 1900 in the Restrict Code Table. (If the same Toll Restriction Class has
both Permit and Restrict Code Tables, the system restricts calls that you
enter only in the Restrict Code Table. Calls entered in both tables are not
restricted.) The system provides 4 tables, with 60 entries (restricted codes)
in each table. A restricted code is 12 digits maximum, using 0-9, #, * and
FLASH (as a wild card).
•
Permit Code Table
The Permit Code Table lets you set up Toll Restriction so that users can dial
only selected (permitted) telephone numbers. Use this table when you want
to restrict most calls. To allow all users to dial only area code 03, for exam-
ple, enter 103 in the Permit Code Table. 1 + 03 + NNX + nnnn are the only
numbers users can dial. (If the same Toll Restriction Class has both Permit
and Restrict Code Tables, the system restricts calls that you enter only in
the Restrict Code Table. Calls entered in both tables are not restricted.) The
system provides 4 tables, with 60 entries (permitted codes) in each table. A
permitted code is 12 digits maximum, using 0-9, #, * and FLASH (as a wild
card).
•
International Call Restriction
International Call Restriction lets you limit the international calls an exten-
sion user may dial. You can build a restrict table to prevent only certain calls,
