Tools that prevent unauthorized calls
You can help prevent unauthorized callers who enter the automated attendant
system from obtaining an outgoing facility by using the security tools shown in
Table 8-1
.
Facility restriction levels
The switch treats all the PBX ports used by automated attendant systems as
stations. Therefore, each automated attendant port can be assigned a COR with
an associated FRL. FRLs provide for eight different levels of restrictions for
AAR/ARS/WCR calls. FRLs are used in combination with calling permissions and
routing patterns and/or preferences to determine where calls can be made. FRLs
range from 0 to 7, with each number representing a different level of restriction (or
no restrictions at all).
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.
