(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 is 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,

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. You can use this
option 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.
Code Call Digit Counting
With Code Call Digit Counting, you can limit the number of digits long distance callers can
dial. This lets you prevent callers from dialing extensively into long distance dial-up
services. You can make four entries (4~30 digits).
Toll Free Trunks
Certain trunks can be completely unrestricted, such as the company
president’s Private
Line. Users can place calls on Code Free Trunks anytime
– to anywhere, without
inadvertently being Code restricted.
PBX Call Restriction
Code Restriction programming lets you enable/disable PBX Call Restriction and enter PBX
access codes. You only need to do this if your system is behind a PBX and you have trunks
programmed for behind PBX operation. Refer to
PBX Compatibility feature for the specifics.
