Disallowed Phone Number Lists (#404)

Description

This System Programming procedure specifies telephone numbers that users cannot dial. For example, you may want to prevent calls to a specific telephone number or to categories of numbers, such as international numbers. Use this procedure to create up to eight lists of up to 10 telephone numbers each.

Related Features

After completing this procedure, you must use Disallowed List Assignments (#405) to assign the Disallowed Phone Number Lists to specific extensions.

Allowed Phone Numbers, Emergency Phone Numbers, and marked System Speed Dial Numbers override the Disallowed List.

The entries you must make to permit or restrict toll calls differ depending on the setting for Toll Call Prefix (#402). This setting tells the system whether a “0” (for operator-assisted calls) or “1” (for direct-dial calls) is required when you make toll calls.

If Star Code Dial Delay (#410) is active, the system checks for allowed and disallowed phone numbers again beginning with the first digit after the star code.

Considerations

Each list entry can include up to 12 digits. You can use the wildcard character (by pressing the hbutton on a system phone) to match any single digit (it appears as “!” on the telephone display).

When a user dials a number that is on a Disallowed List for the user’s extension, the user hears a reorder tone (fast busy signal) after dialing the part of the number that is stored in the list (for example, an area code).

If you want to go to another programming procedure when entering phone numbers in a list, you must use Nor Pto do so since entering #and a three-digit code will be considered data for the telephone number.

Valid Entries

Up to 12 digits including 0–9, #, *, and h(any single digit)
