Restricting Access to Outside Lines

A user can access a line either by pressing a button on the phone or by dialing

a feature code (Direct Line Pickup). If you do not want a user to access a

specific line, use Line Access Restriction (#302) to control an extension’s

access to a certain line. For example, you may want a secretary to answer calls

on a manager’s line, but not to make any outgoing calls on the line; in this case

you can assign the manager’s line to the secretary’s extension and restrict it to

“incoming only.” In addition, you may want to make sure no one else can join

the manager’s line using Direct Line Pickup. To do this, assign “no access” to

that line for all other extensions in the system. The following settings for Line

Access Restriction are available:

■

No restriction.

Outgoing only. The extension cannot receive calls on the line (except

■

transferred calls), but can make outgoing calls.

■

Incoming only. The extension can receive but not make calls on the line.

If you restrict a line on an extension to incoming calls only, the user

cannot select that line to dial out.

■

No access. The extension can see the status of the line (by looking at the

lights), join a call, and pick up a transferred or held call. However, the

extension cannot make or receive calls on the line.

NOTE:

The Line Access Restriction (#302) procedure controls an extension’s access to

an outside line. Once an extension is on an outside line, what it can dial is

controlled by Outgoing Call Restriction and Disallowed Phone Number Lists, an

explained in the next section.

Controlling Calls on Outside Lines

When an extension is allowed access to an outside line, you can use the

following procedures to control calling:

Outgoing Call Restriction (#401) controls calling for all lines available on

■

an extension. You have the following choices:

■

No restriction allows long distance, local, and inside calling.

■

Local only allows local and inside calling only (make sure the Toll Call

Prefix is set properly, using procedure #402).

■

Inside only allows intercom calls only.

Disallowed Phone Number Lists (#404) creates lists of numbers that

■

cannot be dialed. The numbers on a Disallowed List can be entire

telephone numbers, or numbers of a certain type (such as all numbers in

a particular area code). You can store as many as four different lists of up

to 10 numbers each.

After you create the Disallowed Phone Number List(s), use the

Disallowed List Assignment (#405) procedure to assign one or more of

the lists to a specific extension. When a Disallowed Phone Number List

is assigned to an extension, the list applies to all the lines the

extension has access to.
