Class of restriction
Issue 5 October 2002 1643555-233-506
Outward restrictions
You can use outward restrictions to prevent users from placing calls to the public
network. These users can still place calls to other telephone users, to the attendant,
and over tie trunks. If necessary, an attendant or an unrestricted telephone user can
extend a call to an outside number for an outward-restricted telephone user.
When outward restriction is applied to the Calling Party Restriction field on the
Class of Restriction screen, calls coming into a trunk with that COR will be
denied if they make use of the AAR/ARS feature.
Public restrictions
Public restrictions prohibit users from receiving public-network calls. Denied
calls are routed to an intercept tone, a recorded announcement, or the attendant.
Public restrictions still allow users to receive internal calls from other telephones
or calls that were extended from the attendant.
Termination restrictions
You can use termination restrictions to prohibit users from receiving any calls.
These users can still originate calls. DID or Advanced Private-Line Termination
calls route to a recorded announcement or the attendant.
Fully restricted service
Fully restricted service prevents specific users from making or receiving
public-network calls. Fully-restricted users cannot use authorization codes to
deactivate this feature.
Calls from the public network to a fully-restricted extension redirect to intercept
treatment or to the attendant. If the call redirects to the attendant, the attendant’s
display indicates the call was redirected because of fully restricted service
(FULL).
There are circumstances where an extension with fully restricted service can
access or be accessed by the public network.
Miscellaneous terminal restrictions
You can use miscellaneous terminal restrictions to prohibit users from accessing
other specific terminals. Restricted calls are routed to intercept tone.
Miscellaneous restriction groups apply on a per-COR basis. However, you can
assign the same COR to more than one facility. Facilities with the same COR may
be like facilities (such as two telephones) or different facilities (such as a
telephone and a trunk group)
