Facility restriction levels
The switch treats all the PBX ports used by voice mail systems as stations.
Therefore, each voice mail port can be assigned a COR/COS with an FRL
associated with the COR/COS. FRLs provide eight different levels of restrictions
for AAR/ARS/WCR calls. They 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.
The higher the FRL number, the greater the calling privileges. For example, if a
station is not permitted to make outside calls, assign it an FRL value of 0. Then
ensure that the FRLs on the trunk group preferences in the routing patterns are
1 or higher.
For example, when voice mail ports are assigned to a COR with an FRL of 0,
outside calls are disallowed. If this is too restrictive because the Outcalling feature
is being used, the voice mail ports can be assigned to a COR with an FRL that is
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.
Station-to-trunk restrictions
Station-to-trunk restrictions can be assigned to disallow stations from dialing
specific outside trunks. By implementing these restrictions, callers cannot transfer
out of voice mail to an outside facility using trunk access codes.
For G2 and System 85, if TACs are necessary for certain users to allow direct dial
access to specific facilities, such as tie trunks, use the Miscellaneous Trunk
Restriction feature to deny access to others. For those stations and all
trunk-originated calls, always use ARS/AAR/WCR for outside calling.
NOTE:
Allowing TAC access to tie trunks on your switch may give the caller access
to the Trunk Verification feature on the next switch, or the outgoing trunks
through either ARS or TACs.
