The higher the station 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 automated attendant ports are assigned to a COR with an
FRL of 0, outside calls are disallowed. If that is too restrictive, the automated
attendant ports can be assigned to a COR with an FRL that is low enough to limit
calls to the calling area needed.
NOTE:
Stations that are outward restricted cannot use AAR/ARS/WCR trunks.
Therefore, the FRL level does not matter since FRLs are not checked.
Station-to-trunk restrictions
Station-to-trunk restrictions can be assigned to disallow the automated attendant
ports from dialing specific outside trunks. By implementing these restrictions,
callers cannot transfer out of the Automated Attendant menu to an outside facility
using trunk access codes.
For DEFINITY 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. If not properly
administered, the caller may be able to dial 9 or the TACs in the other
switch.
Class of restriction (System 75, DEFINITY G1,
and G3, Communication Manager,
MultiVantage Software, DEFINITY ECS)
Since automated attendant adjunct equipment is considered an extension to the
switch, it should be assigned its own COR. Up to 64 CORs can be defined in the
system. For DEFINITY G3rVi, G3i-Global, and G3V2, this has been increased to
96 CORs.
The CORs are assigned to stations and trunks to provide or prevent the ability to
make specific types of calls, or calls to other specified CORs. For example, the
automated attendant extension could be assigned to a COR that prohibits any
outgoing calls.
