Magix R1.5: Disallowed Lists Enhancements
Consider the following when you use wild card characters in 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 wild card character) matches dialed numbers of “267,” “367,” etc., but
not “167.”
 When a dialed number is compared to an entry in the Disallowed List, the
leading “1” is not dropped. Thus, a Disallowed List entry of “p67” matches
dialed numbers of “167” and “267,” “367,” etc.
 You cannot use a wild card character to match a * or # in an Allowed List
or a Disallowed List.
 A wild card character in any position in a Disallowed List entry matches
dialed number 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.
 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.
