Feature Reference
Class of restriction
•
Call Forwarding All Calls
If a call is restricted between the forwarding and forwarded-to extensions, Call Forwarding is
denied. Restrictions are always checked when Call Forwarding is activated, but not when a call is
forwarded.
•
Call Vectoring
When a call is directed to a VDN extension, the COR of the caller and the VDN are compared to
determine if the caller can access the associated call vector.
•
Class of Service (COS)
In some cases, the COR can be overridden by the COS. See the
field documented with the
•
Controlled Restriction
Restrictions assigned via Controlled Restriction override COR restriction.
•
Emergency Access to Attendant
Emergency Access to Attendant calls are not restricted by COR.
Interactions for called-party and calling-party restrictions
•
Night Service
Night Service and Night Station — Trunk Answer From Any Station override Inward, Manual
Terminating Line, and Public Restrictions.
•
Tie-Trunk Access
Incoming dial-repeating tie-trunk calls can be completed directly to an inward-restricted or
public-restricted extension but cannot be extended by an attendant to an inward-restricted
telephone.
•
Transfer
Incoming trunk calls cannot be transferred to an inward-restricted extension when a 3-way COR
check is made.
Incoming trunk calls can be transferred from an unrestricted extension to an inward-restricted or
public-restricted extension if the 3-way COR check on Conference is overridden.
Interactions for fully restricted service restrictions
•
Centralized Attendant Service (CAS)
Since COR information is not passed over Release Link Trunks (RLT), fully restricted service
allows all CAS calls. Therefore, CAS allows a public network call to complete to a
fully-restricted station.
•
Distributed Communications System (DCS)
Fully Restricted Service allows all DCS calls because COR information is not transparent for
DCS. DCS can allow a public network call to be completed to a Fully Restricted station.
•
Power Failure Transfer
All authorization features are bypassed when the switch is in Emergency Transfer Mode.
•
Hunt Group
The COR assigned to the Hunt Group is checked on calls redirected by the DDC or UCD of the
hunt group. Extensions in the hunt group that have Fully Restricted Service can receive calls from
the public network (via the hunt group) if the COR of the Hunt Group does not have Fully
Restricted Service.
