Voice Messaging Systems
6-6 Issue 7 June 2001
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.
Class of Restriction
For DEFINITY ECS, DEFINITY G1, G3, and System 75, each voice port on the
voice mail adjunct is considered an extension to the switch and should be
assigned its own unique COR. Up to 64 CORs can be defined in the system. For
DEFINITY G3rV1, G3i-Global, and G3V2 and later, 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, a voice mail extension could be assigned to a COR that prohibits any
outgoing calls.
