Dialing Restrictions and Permissions

Disallowed Number Lists

A disallowed numbers lists specifies telephone numbers that extensions associated with the list cannot dial. You can create up to eight disallowed number lists each containing up to 10 telephone numbers.

For example, you may want to prevent calls to a specific telephone number or to categories of numbers, such as international numbers.

A Disallowed Phone Number can be up to 12 digits long and may include 0–9 or a wildcard ? character to represent any digit.
Numbers in a disallowed list are overridden by allowed numbers, emergency numbers and marked system speed dial numbers.
When a user dials a number that is on a disallowed list, they hear an intercept tone (fast busy signal) after dialing the part of the number that is stored in the list.
To restrict dialing specific telephone numbers, enter the telephone number exactly as you would dial it. For example, to prevent calls to the local number 555-5678, enter 5555678.
To restrict dialing numbers in an entire area code, enter that area code exactly as you would dial it; for example, 900, 1900 or 0900 depending on the Toll Call Prefix required. This setting tells the system whether a 0 (for operator-assisted calls) or a 1 (for direct-dial calls) is required when you make toll calls.
To prevent dialing all telephone numbers in one exchange when a toll prefix is required:

Entry

Restriction

976

Prevents local calls.

1???976

Prevents direct-dial calls to the specified exchange in all area codes.

0???976

Prevents operator-assisted calls to the specified exchange in all area codes.

1976

Prevents direct-dial toll calls in the same area code. This is needed only when 0 or 1 is required for toll calls in the same area code.

0976

Prevents operator-assisted toll calls in the same area code. This is needed only when 0 or 1 is required for toll calls in the same area code.

To prevent dialing all telephone numbers in one exchange when no toll prefix is required:

Entry

Restriction

976

?0?976

Prevents calls to area codes with 0 as the second digit, such as 203.

?1?976

Prevents calls to area codes with 1 as the second digit, such as 212.

To prevent international calls, enter the international prefix number, 011.
To prevent the use of all star codes enter *.
To prevent the use of a specific star code, for example *67 to block Caller ID information, enter the * plus the 2- or 3-digit code.
The entries you must make to permit or restrict toll calls differ depending on the setting for Toll Call Prefix.
