Allow Calling Only to Specified Numbers
A reverse strategy to preventing calls is to allow outbound calls only to certain
numbers. For G1 and System 75, you must specify both the area code and the
office code of the allowable numbers. For G3, you can specify the area code or
telephone number of calls you allow.
For DEFINITY G1 and System 75:
 Use change ars fnpa xxx to display the ARS FNPA Table, where xxx is
the NPA that will have some unrestricted exchanges.
 Route the NPA to an RHNPA table (for example, r1).
 Use change rnhpa r1: xxx to route unrestricted exchanges to a pattern
choice with an FRL equal to or lower than the originating FRL of the voice
mail ports.
 If the unrestricted exchanges are in the Home NPA, and the Home NPA
routes to
h on the FNPA Table, use change hnpa xxx to route unrestricted
exchanges to a pattern with a low FRL.
NOTE:
If assigning a low FRL to a pattern preference conflicts with requirements for
other callers (it allows calls that should not be allowed), use ARS partitioning
to establish separate FNPA/HNPA/RHNPA tables for the voice mail ports.
For DEFINITY G2 and System 85:
 Use PROC311 WORD2 to establish 6-digit translation tables for foreign
NPAs, and assign up to 10 different routing designators to each foreign
NPA (area code).
 Use PROC311 WORD3 to map restricted and unrestricted exchanges to
different routing designators.
 If the unrestricted toll exchanges are in the Home NPA, use PROC311
WORD1
to map them to a routing designator.
 If the Tenant Services feature is used, use PROC314 WORD1 to map
routing designators to patterns. If Tenant Services is not used, the pattern
number will be the same as the routing designator number.
 Use PROC309 WORD3 to define the restricted and unrestricted patterns.
