Disallowed Lists
Use this procedure to establish Disallowed Lists. These lists are telephone
numbers that cannot be dialed from specified telephones (including unrestricted
telephones).
A maximum of 8 lists (numbered 0 through 7) with 10 entries each (numbered 0
through 9) are allowed. Each number can have a maximum of 11 digits,
including wildcards. The Pause character (entered by pressing the Hold button)
is used to designate a wildcard character, for example, to indicate that calls to a
given exchange are restricted in every area code.

Security Alert:
Create a Disallowed List or use the pre-prepared Disallowed List number
7 (Release 3.1 and later systems only) to disallow dialing 0, 11, 10, 1700,
1809, 1900, and 976 or 1(wildcard)976. In Release 3.1 and later systems,
Disallowed List number 7 does not include 800 and 1800 and 411 and
1411, but AT&T recommends that you add them. Assign all voice mail
port extensions to this Disallowed List. AT&T recommends assigning
Disallowed List number 7. This is an added layer of security, in case
outward restriction is inadvertently removed. (In Release 3.1 and later
systems, voice messaging ports are assigned by default to Disallowed
List number 7.)
