1305Class of Restriction

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 ca n redi rect t o

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

(WA TS) c alls are routed t o the attend ant. DID c alls are r outed to a n announc ement

or the attendant. Telephone calls are routed to intercept treatment.

Origination restrictions

You can use origination restrictions to prohibit users from originati ng 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 user s, to the a ttendant ,

and over tie trunks. If necessary, an att endant or an unre stricted t elephone u ser ca n

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 c alls from other telephones

or calls that were extended from the attendant.
