Night Service With Outward Restriction - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Features
Beginning with Release 3.1, star codes can be included in Allowed and
Disallowed Lists (in Releases 3.0 and earlier, the system treats star codes no
differently from other dialed digits, and you cannot include a star code in an
Allowed/Disallowed List; this can affect calling restrictions and ARS routing).
Furthermore, they are ignored by the Automatic Route Selection feature when
routing calls. Star codes, typically dialed before an outgoing call, provide
special services from the CO. For example, in many areas a telephone user can
dial before a telephone number to disable central office-supplied caller
identification at the receiving party's telephone. To allow or disallow use of this
star code preceding a call, you include *67 in an Allowed or Disallowed List. For
each star code, a separate list entry is required. For more information about
star codes in Allowed/Disallowed Lists, see Chapter 6, "Managing the System."
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 single-line telephones
*, to prevent the use of star codes at multiline telephones
