2 - 232 Code Restriction

 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

(permitted) telephone numbers. Use this table when you want to restrict most calls. To

allow all users to dial only area code 203, for example, enter 1203 in the Permit Code

Table. 1 + 203 + NNX + nnnn 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 has 12 digits maximum, using 0~9,

#,  and Recall (as a wild card).

 International Call Restriction

International Call Restriction lets you limit the international calls an extension user may dial.

You can build a restrict table to prevent only certain calls, or you can build a permit table to

allow only certain calls. To allow most international calls, use the International Call Restrict

Table. To prevent most international calls, use the International Call Allow Table. The

system provides 10 International Call Restrict tables with up to four digits in each table

entry and 20 International Call Allow tables, with up to six digits in each table entry. Valid

entries are 0~9,

#,  and Recall (for a wild card).

 Code Restriction for Speed Dialing

Speed Dialing can bypass or follow Code Restriction. If you allow many users to program

Speed Dialing, consider code restricting the numbers they dial. If only administrators can

program Speed Dialing, Code Restriction may not be necessary. You can separately

restrict Group and Common Speed Dialing.

 Toll Digit Counting

Use Call Digit Counting to limit the number of digits local callers can dial. Use this to

prevent users from accessing local dial-up services. For example, set the Maximum

Number of Digits in Local Calls to seven to limit local callers to dialing the exchange code

(NNX) and local address (nnnn) only. The system provides four tables in which you can

make entries for this option. The range is 4~30 digits.
