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

[ 4 ] [ 1 ] [ 1] [ Enter ]..
