Dialing Features - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Features
Toll fraud is a growing criminal industry, and there are individuals who have
made a science of defrauding businesses of millions of dollars. You should
strongly caution users against the following practices that can compromise the
security of the system:
Writing down barrier codes or passwords and keeping them in a wallet or
purse
Making remote access calls or other password-protected calls from
public telephones in such a way that they can be viewed by others, who
may even use telescopes or binoculars to see the digits as they are
dialed
Sharing barrier codes or passwords with others or saying them out loud
in public locations
Programming passwords or barrier codes on telephone buttons inside or
outside the system
For more information about security, see "Remote Access" and "Voice
Messaging Systems," later in this chapter.

Dialing Features

Dialing features are straightforward, providing a variety of methods for fast
dialing of frequently used numbers. Review the dialing features by looking at
"Dialing and Calling" in Table 4–1, earlier in this chapter. The analog multiline
and cordless/wireless telephone user's and operator's guides include forms for
recording dial codes ( not passwords or barrier codes) that people use often.
MLX telephones come with tray cards for this purpose.
When considering dialing features for an extension, keep the following factors in
mind:
Operators often need Direct Station Selectors (DSSs) for easy access to
extensions. Auto Dial is also an option when the operator does not cover
a large number of extensions.
Auto Dial buttons require programmed line buttons but are useful for
people who have those buttons available and make many calls to a few
numbers. They are also useful for entering account codes and other
dialed codes and may be appropriate for people who frequently enter the
same codes.
MLX display telephone users can take advantage of Directory features for
calling frequently used numbers.
