6 Managing the System
Revising Disallowed Lists
The star code or codes must come at the beginning of the string of digits
dialed, not at the end or in the middle. Multiple leading star codes are
allowed for dialing, but not in Allowed/Disallowed Lists. For example,
*67*705551212 is recognized correctly, but in 5551212*67*705553131 the
stars are ignored.
To prevent rotary phone users from using all star codes, include a separate
Disallowed List entry, 11 . To disallow specific codes, create separate
entries where 11 is substituted for the *, for example, 1167 .
Beginning with Release 3.1, a default Disallowed List (number 7) is provided with
the system. This Disallowed List is automatically assigned to both generic and
integrated VMI ports used by voice messaging systems. It includes the following
entries, which are often used for toll fraud:
0, to prevent international calls
10, to prevent access to long-distance service providers
1809, to prevent unauthorized international calls routed through the
Dominican Republic
1700, to prevent unauthorized toll calls with a "700" area code
1900, to prevent unauthorized toll calls with a "900" area code
976, to prevent local toll calls to numbers with "976" local access codes
1www976, where "w" stands for a wildcard entry, to prevent long-distance
calls to numbers with "976" local access codes
11, to prevent the use of star codes at rotary telephones
*, to prevent the use of star codes at multiline telephones
Valid Entries
11 digits for each number (+ wildcard Pause character, entered by pressing the
Hold button)
Asterisk (*) or star or 11 (Release 3.1 and later systems only) a maximum of one
leading star code in each entry
10 numbers for each list (numbered 0 through 9)
8 lists for each system (numbered 0 through 7)
8 lists for each telephone
