AT&T at&t partner plus communications system manual Prevents all ca!ls to area code

The entries for toll calls differ, depending on the Toll Call Prefix (#402). Make sure the Toll Call Prefix is set correctly for your dialing area. If it is not, entries on the Disallowed and Allowed Phone Number Lists may not be handled correctly.

Programming Notes: To program telephone numbers, dial the number as you would normally. You can also use the "wildcard” character to stand for any digit in a phone number. For example, if you want to prevent users from making calls to area codes 202 and 212, you could enter each area code separately or com- bine them in one entry using the wildcard to stand for the middle digit. Using the wildcard, you would press [ 2 ] [ Wild ] [ 2 ] . The wildcard character appears as a “!” on the display: 2 ! 2

When you use the wildcard, be sure that you do not inadvertently prevent a call that should be allowed. In the example above, if we do not include a toll prefix (1 or 0), this entry would prevent calls to exchanges 222, 232, 242, 252, 262, 272, 282, and 292 as well as area codes 202 and 212, since the wildcard matches any digit. The examples below include normally-dialed numbers and wildcards.

■Specific Telephone Numbers. Dial the telephone number directly, followed by [ Enter ] . For example, to prevent calls to local directory assistance, press [ 4 ] [ 1 ] [ 1] [ Enter ]..
