Inward restrictions
You can use inward restrictions to permit users to receive only internal calls.
Inward restrictions prohibit users at assigned telephones from receiving
public-network, attendant-originated, and attendant-extended calls.
The COR of the originally-called extension is the only one checked unless you
administer 3-way COR check on conference and transfer calls. Denied calls are
routed to intercept tone, a recorded announcement, or the attendant for Direct
Inward Dialing (DID) calls.
Manual terminating line restrictions
You can use manual terminating line restrictions to allow users to receive calls
only from an attendant or that were extended by an attendant. Calls can redirect to
a manual terminating line-restricted telephone. The COR of the originally-called
extension is the only one checked.
Local CO, foreign exchange (FX), and Wide Area Telecommunications Service
(WATS) calls are routed to the attendant. DID calls are routed to an announcement
or the attendant. Telephone calls are routed to intercept treatment.
Origination restrictions
You can use origination restrictions to prohibit users from originating calls. These
users can still receive calls.
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 form, 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.
