	Calling Restrictions	4

This section contains instructions to restrict selected extensions from making outside calls — for example, for telephones in a reception area and to control toll-call abuse  but still allow local and intercom calls.

!SecurityAlert:

Calling restrictions [for example, Disallowed Lists, toll restriction, Facility Restriction (FRL) Levels] should be programmed, as appropriate, to minimize toll fraud abuse. Refer to the “Calling Restrictions” section in the Feature Reference for additional information on programming calling restrictions.

Planning Form Instructions

If these restrictions are too limited, use “Allowed Lists” and “Disallowed Lists,” as described later in this chapter.

Use Form 6h to identify Authorization Codes for use by the users of certain extensions. After Form 6h is filled in, remove it from the forms set and keep it in a secure place.

Use Form 6g, Call Restriction Assignments and Lists, to identify the extensions with calling restriction assignments. List the extensions with calling restrictions in the Ext. No. column and the type of restriction in the Restriction Type column. The factory setting is Restricted.

NOTE:

Setting this option to Outward Restrict or Toll Restrict does not allow reliable toll restriction on telephone company lines/trunks that do not require 1 or 0 for toll calls. The Toll Type setting of 1 or 0 allows the system to classify calls as either local or toll, based on the number a user dials. Dialing a prefix depends on local telephone company requirements and the type of trunk being used. The system must be programmed to designate whether or not to restrict users from dialing calls to certain areas. The Toll Type feature does not apply to DID trunks or private network tandem trunks.

To restrict the extension from making outside calls so only intercom or private network calls can be made, check the Outward Restriction column.

To restrict the extension from making toll calls so only intercom, local, or private network calls can be made, check the Toll Restriction column.
