Code Restriction/Toll Restriction
Description
Code Restriction/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 Code Restriction according to the Code Restriction Class. The system allows for up to 15
Code Restriction Classes and 128 extensions.
Conditions
• If a Code Restriction Class has the same entries in both a permit and restriction table, the system
does not restrict the call.
• Code Call Digit counting may prevent users from taking advantage of long distance automated
services like ACD and automated Technical Service.
• Code Restriction is applied when accessing ARS.
• If PRG 21-01-10 is programmed with an entry other than 0, a call cannot have a talk path unless the
user dials at least the number of digits entered in this option when placing an out going call. This
means that an entry of 4 or higher in this program causes a problem when dialing 999 or 112. Since
these are only 3-digit numbers, the call does not have a talk path, preventing the emergency
dispatcher from hearing the caller. This option should be kept at its default setting of 0 to prevent
any problem with dialing 999 or 112.
• Common Permit Code Table
Use the Common Permit Code Table when you have numbers you want all Code Restriction
Classes to dial. To let all users dial 999 or 112, for example, put 999 & 112 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 four digits
maximum, using 0~9, #,
*
and Flash key (as a wild card).
• Common Restrict Code Table
The Common Restrict Code Table lets you globally restrict certain numbers for all Code Restriction
Classes. Be sure you do not 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 four digits maximum, using 0~9, #,
*
and Flash key (as a wild card).
• Restrict Code Table
When you want Code 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 Code 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 four tables, with 60 entries (restricted codes) in each table. A restricted code is 12
digits maximum, using 0~9, #,
*
and Flash key (as a wild card).
• Permit Code Table
The Permit Code Table lets you set up Code 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 01203, for example, enter 01203 in the Permit Code Table. 01203 +
(digits) are the only numbers users can dial. (If the same Code 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 four tables, with 200 entries
(permitted codes) in each table. A permitted code is 12 digits maximum, using 0~9, #,
*
and Flash
key (as a wild card).
