Calling Privileges And Restrictions - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Features

Calling Privileges and Restrictions

Calling privileges and restrictions are planned and programmed centrally for the
extensions in your company, as well as for remote access users. When you add
a new extension or make other changes in your system, you may need to add or
change calling restrictions. You should also consider security issues when you
decide whether to allow the system to forward calls to an outside number or
when you plan for voice mail systems. See "Security" in this chapter and
Appendix A, "Customer Support Information," for more information about
security planning and procedures.
Although the features described in Table 4–3 affect individual users, controlling
calling privileges is a system management function.
Do Not Disturb and Privacy are not calling restrictions, but are included here
because they prevent calls to individual extensions.
NOTES:
1. If your system operates in Behind Switch mode with a Centrex service
providing features, Centrex (and not system) calling restrictions must be
used.
2. The Authorization Codes feature enables users to apply the calling
restrictions of their own extensions when they need to make calls from more
restricted phones. For more information, see "Authorization Codes," later in
this chapter, or the Feature Reference .
3. In Release 4.0 and later systems, the system manager can remove one of
the line buttons (SA or ICOM) assigned to an extension where there is a
single-line telephone. This feature is designed to accommodate hotels and
other institutions, where organizations do not want calls transferred from
guest extensions. Removing one of the buttons prevents Privacy from being
used at the extension.
4. In Release 3.1 and later systems, default settings for calling restrictions help
system managers guard against toll fraud. For more information, see the
topics "Calling Restrictions," and "Security," later in this chapter.
