Code Restriction
Description
Code 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
960 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 Contact Centre and automated Technical Service.
Code Restriction is applied when accessing ARS.
If Program 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 911. Since it is only a 3-digit number, 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 911.
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 911, for example, put 911 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 up to four digits in
each table entry. Each code is four digits maximum, using 0~9, #, Q and Recall (as a wild
card).
Common Restrict Code Table
The Common Restrict Code Table lets you globally restrict certain numbers for all Code
Restriction Classes. To prevent all users from dialing directory assistance (411), for
example, put 411 in the Common Restrict Code Table. 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 up to four digits in each table entry. Each code is 12 digits
maximum, using 0~9, #, Q and Recall (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 Recall (as a wild
card).
Permit Code Table
The Permit Code Table lets you set up Code Restriction so that users can dial only selected
