during the pause.
■ Station Message Detail Recording (SMDR). This system management
feature keeps track of incoming and outgoing calls and prints out reports on
a printer attached to your control unit. It also prints programming reports
that can alert you to tampering with the system. Inspect these reports
frequently. (Call Accounting System applications also provide a utility for
detecting toll fraud. See Table 4–12 on page 4-57
.)
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’’ on page 4-53 and
‘‘
Voice Messaging Systems’’ on page 4-60.
Dialing Features 4
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 on page 4-5
. 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.
