Restriction override (3-way COR check)
The Restriction Override feature, which is available only with DEFINITY
G3i-Global and G3V2 and later, determines whether or not there is a 3-way COR
check made on conference and transfer calls.
For DEFINITY G3 systems prior to DEFINITY ECS Release 5, as well as for G1
and System 75 systems, the default value of the
Restriction Override field
on the COR screen is
all. Starting with DEFINITY ECS Release 5, the default
value of the field is
none for all CORs. This helps ensure that the feature is
assigned only when appropriate.
If
Restriction Override=all, only the controlling party’s COR is checked
against the CORs of all other parties on the conference and/or transfer call for
station-controlled transfers and conferences, not attendant-controlled
conferences and attendant-extended calls. If
Restriction Override=none,
the new party’s COR is always checked against the CORs of all other parties on
attendant extended calls and attendant-controlled conferences, as well as on all
station-controlled conferences and transfers.
Class of service
For DEFINITY G2 and System 85, station access to various switch features is
controlled by options in the Class of Service (COS) associated with the extension
number. The following COS options are related to toll fraud prevention:
■ Call Forward Off-Net: allows a user to call forward outside the switch to
non-toll locations (G2.1). In G2.2, the user may be allowed to forward to a
toll location (including international destinations), depending on the
permissions and restrictions for that extension, as defined in PROC000,
WORD3, FIELD7.
■ Call Forward Follow Me: allows a user to forward calls outside the switch
when other options are set.
■ Miscellaneous Trunk Restrictions: restricts certain stations from calling
certain trunk groups via dial access codes.
■ APLT Off-Net: allows callers to dial public network numbers over the
EPSCS private network.
■ Terminal-to-Terminal Restriction: restricts the user from placing or receiving
any calls except to and from other stations on the switch.
■ Outward Restriction: restricts the user from placing calls over the CO, FX,
or WATS trunks using dial access codes to trunks. Outward restriction also
restricts the user from placing calls via ARS/WCR. Use ARS/WCR with
WCR toll restrictions instead.
■ Toll Restriction: prevents users from placing toll calls over CO, FX, or
WATS trunks using dial access codes to trunks. Use ARS/WCR with WCR
toll restrictions instead.
