The FRL is used for the AAR/ARS/WCR feature to determine call access to an
outgoing trunk group. Outgoing call routing is determined by a comparison of the
FRLs in the AAR/ARS/WCR routing pattern to the FRL associated with the
COR/COS of the call originator.
The higher the FRL number, the greater the calling privileges. For example, when
voice mail ports are assigned to a COR with an FRL of 0, outside calls are
disallowed. If that is too restrictive, the voice mail ports can be assigned to a
COR with an FRL that is higher, yet low enough to limit calls to the calling area
needed.
NOTE:
Voice Messaging ports that are outward restricted via COR cannot use
AAR/ARS/WCR trunks. Therefore, the FRL level doesn’t matter since FRLs
are not checked.
FRLs can be assigned to offer a range of calling areas. Choose the one that
provides the most restricted calling area that is required.
Table 1 provides suggested FRL values.
Table 1. Suggested Values for FRLs
NOTE:
In Table 1, FRLs 1 through 7 include the capabilities of the lower FRLs. For
example, FRL 3 allows private network trunk calls and local calls in addition
to FX and WATS trunk calls.
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.brtrunks.
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.
