4Features and Applications

Features Page 4-42

■Some voice messaging systems (described later in this chapter) permit outcalling. That is, these systems can be programmed to call an outside number to deliver messages or faxes. This feature can be used for toll abuse, so consider calling restrictions for lines used by such systems.

■Remote Call Forwarding can be allowed or disallowed for your system. If allowed, a user can have calls forwarded to an outside number. (This is not permitted at extensions or on lines where calling restrictions have been applied.)

■When restrictions are applied to extensions, rather than to lines/trunks, a person can ask a co-worker or operator with fewer restrictions to make a toll call on his or her behalf.

■Authorization codes are intended to allow people with less restricted extensions to use extensions where there are more restrictions. If you use authorization codes to enforce restrictions, people may discover that, at some extensions, they can make calls without using authorization codes and gain more privileges than their own extensions allow.

The sections below list the types of restrictions, including the following information:

■Whether the restriction is applied to an extension, line, remote access barrier code (acting as an “extension” for a remote access user), or a combination

■What other restriction features it works in conjunction with, as well as mode restrictions

■A brief description, including recommended use

Since there is some interaction among these features and with other system features, refer to the Feature Reference for more detailed information.

Outward and Toll Restrictions

Apply to: Lines/trunks, especially those used for remote access or for outcalling

by a voice messaging system (see ‘Voice‘ Messaging Systems’’ on page 4-60), excluding tie and emulated tie trunks programmed as Tie-PBX for Hybrid/PBX mode extensions.

Use with: Allowed Lists to permit restricted users to make some calls. (Tagged System Speed Dial codes or their corresponding tagged Directory listings can also be used to make certain calls.) Can be used with any other calling restrictions.

An extension, line/trunk, or remote access user’s barrier code can be programmed to prevent either all outside calls or outside toll calls only. In Release

3.1and later systems, ports assigned for use by voice messaging systems (generic or integrated VMI ports) are assigned outward restrictions by default. If a voice messaging system is allowed to call out (for example, to send calls to a user’s home office), the system manager should remove these restrictions.
