Limit Voice Mail to Internal Calling
If outcalling is not activated in the voice mail system, you can restrict voice mail
callers from dialing an outside number by making the ports outward restricted.
For DEFINITY G1, G3, and System 75:
Use change cor to display the Class of Restriction screen, then create an
outward restricted COR by entering
outward in the Calling Party
Restriction field.
Assign FRL 0.
Use change station to assign the outward restricted COR to the voice mail
ports.
Use COR-to-COR restrictions to block voice mail ports from directly
accessing the CORs of outgoing trunks. The trunk CORs should be unique.
For DEFINITY G2 and System 85:
Use PROC010 WORD3 FIELD19 to assign outward restriction to the voice
mail ports’ COS.
Make the voice ports Toll Restricted and ARS Toll Restricted, and assign
an FRL of 0. Enter
no for all Miscellaneous Trunk Restriction Groups
(MTRGs).
Restrict the Outside Calling Area
When you assign the lowest possible FRL to the voice mail ports, you can limit the
trunks that are available to callers. FRLs can be assigned to offer a range of
calling regions. Choose the one that provides the most restricted calling range
that is required. Table 6-2 provides suggested FRL values.
Table 6-2. Suggested Values for FRLs
FRL Suggested Value
0 No outgoing (off-switch) calls permitted.
1 Allow local calls only; deny 0+ and 1 800 calls.
2 Allow local calls, 0+, and 1 800 calls.
3 Allow local calls plus calls on FX and WATS trunks.
4 Allow calls within the home NPA.
5 Allow calls to certain destinations within the continental USA.
6 Allow calls throughout the continental USA.
7 Allow international calling. Assign attendant console FRL 7. Be
aware, however, if Extension Number Portability is used, the
originating endpoint is assigned FRL 7.
