Toll restrictions allow or prevent specific numbers from being dialed out. This Tech Tip demonstrates how to assign a toll restriction class to an individual extension. This applies to the NEC SL2100 and SL1100 phone systems.

Example Overview
In this example, we will create a toll restriction class for Extension 101 that only allows dialing 911. All other dialing will be blocked using the wildcard restriction.
Programming Steps
- Go to Program 21-04: Toll Restriction Class for Extension
Mode 1 will be our “Day Mode,” and Mode 2 will be our “Night Mode.”- Set the value of Mode 1 to
1for Extension101
- Set the value of Mode 1 to
- Go to Program 21-05: Toll Restriction Class
- Set 21-05-07: Permit Code Table to
1 - Set 21-05-08: Restriction Table to
1
- Set 21-05-07: Permit Code Table to
- Go to Program 21-06-06: Toll Restriction – Permit Code Table
In this program, all tables and entries are blank by default. You may create up to 4 different Permit Code Tables, each with up to 200 entries.- For Table Entry
001, set the Dial Digits to911
This allows dialing of 911 only.
- For Table Entry
- Go to Program 21-06-07: Toll Restriction – Restrict Code Table
This program allows you to define up to 4 Restriction Tables with up to 60 entries each. It supports wildcards for broad restrictions.- For Table Entry
01, set the Dial Digits field to@
The@symbol is a wildcard that blocks any digits not explicitly allowed in the permit table.
- For Table Entry
- Apply and upload your changes
⚠️ Note:
Using the @ wildcard blocks all outbound dialing except for numbers explicitly permitted. In this example, only 911 will be allowed.
