Exercise 12: Basic Toll Restriction

Pre-Setup Discussion

The exercise discusses a simple toll restriction scenario, including programming and testing its

operation. The items you must program in VMMI are located in several places. Follow the steps

in this exercise carefully.

Operation

Comdial’s toll restriction works in a unique way.

1. When a system user (extension 1001) dials a number on a CO line, the system looks for a

match in the Restriction tables. If it finds no match, it allows the call. If it finds a match, it

goes to the next step.

2. In this step the Comdial system looks at the Toll Group entry in the matching Restriction

table. If the line used for the call is in the matching toll group, then it goes to the next step.

If there is no match, the call is allowed.

3. In this step the Comdial system looks at the restriction level in the matching Restriction

table:

• If the restriction level is set to “allow all” the call goes through.

• If the restriction level is set to “deny all” the system goes to the next step.

• If the restriction level is set to a value 1 to 8, it compares the restriction level assigned to

the extension through Class of Service programming to the restriction level assigned to a

specific dialed number in the Restriction tables. If the extension’s restriction level is

greater than or equal to the restriction level in the Restriction table, the call is allowed. If

it is less than the restriction level, it goes to the next step.

4. The Comdial system looks at the exception number field in the matching restriction table:

• If there is a 0, there is no exception to the rule, and the call is denied.

• If there is a 1-32, the system looks in Station / Exception Number programming

(extension 1001) for a match. If it finds a match, the call is allowed. If no match is

found, the call is denied.
