Consider the following when you use wildcard characters in allowed and
disallowed lists:
■ Disallowed list entries can be from 1 to 12 characters in length.
■ Before a dialed number is compared to an entry in the allowed list, the
leading “1” is dropped. Thus, an allowed list entry of “p67” (where “p” is the
wildcard character) matches dialed numbers of “267,” “367,” etc., but not
“167.”
■ You cannot use a wildcard character to match a * or # in an allowed or
disallowed list.
■ A wildcard character in positions 2–13 in an allow list entry matches dialed
numbers 0–9 when the dialed number is not part of a star code.
NOTE:
A star code is a central office code used to perform a specific function, such
as
*70 to disable call waiting.
■ A wildcard character in position 1 in an allowed list entry matches dialed
number 0 and 2–9.
■ If a star code is an entry in an allowed or disallowed list, that entry should
only have the star code because anything entered in the list after the star
code is ignored by the system. The following entries are valid:
—*67
—*69
—*70
—*200
The following are examples of entries that should not be placed in the allowed or
disallowed list:
— *67201
— *69914
— *702125551212
— *2004319255
■ If a star code is an entry in an allowed or disallowed list and a dialed
number matches the star code, the allowed/disallowed process is reset
after the match is done. Any digits dialed after the star code are compared
to entries in the allowed/disallowed lists for restriction processing.
For example:
*67 and 420 are two entries in an allowed list. If someone at an
outward restricted extension dials
*67 420-1234, the call succeeds. If the person
at the same outward restricted extension dial
*67 431-1234, the call fails (431 is
not in the allowed list). If the person at the same extension dials 420-1234, the call
succeeds. This type of processing also applies to disallowed lists.
