Restriction filters

Restriction filters prevent you from making certain kinds of calls from a telephone

or from lines that are available at the telephone. They also restrict some features.

The following illustration shows the Restriction filters programming map.

Filters

A restriction filter is a set or group of restrictions and overrides that specify the

external numbers or feature codes that cannot be dialed from a telephone or on a

line. Rather than define individual restrictions and apply them repeatedly to

telephones and to lines, the restriction filters setting Allows you to assign them in

one step as a single package of dialing sequences that are not permitted.

In addition to restricting telephone numbers, you can prevent people from entering

dialing sequences used by the central office (the public network) to deliver special

services and features. Because some of these features provide the caller with dial

tone after they have entered the special code (which often uses # or *), users may

have an opportunity to bypass restrictions. To prevent this from happening, you can

create filters that block these special codes.

You createa filter by defining the dialing sequences that are denied. There will also

be variations of each sequence that you will want users to be able to dial. Sequences

that can be dialed are called overrides.

Once you create the filters, you can assign the restrictions to a telephone

(Terminals & sets), to a line (Lines), to a particular line on a telephone (Terminals

&sets), and to remote callers (Lines, Remote access).

Note: Filter 00 cannot be changed; filters 02—04 have default settings; see

Default filters (North America) on page 125.

To program a restriction filter:

1. Choose Services, Telephony Services, Restriction filters.

2. Expand the restriction filter you want to program (Filter 00-99). Click on the

Restrictions heading.

3. Click Add above the navigation tree to enter a restriction for each filter.

The Add restrictions dialog box appears.
