■ An authorization code can also be used to remote call forward calls at
phantom extensions.
■ Authorization codes can be used for call control and call accounting
through the Station Message Detail Recording (SMDR) printout. However,
if the user enters both an authorization code and an account code, the
account code takes precedence and is stored in the SMDR record.
For more information about authorization codes, see the Feature Reference.
SECURITY l ALERT:
!
Authorization codes are not designed to function as a security measure
against toll fraud. For information on system security, see the next section,
“Security,” and “Security of Your System: Preventing Toll Fraud,” in
Appendix A, “Customer Support Information.”
Security 4
Most security issues are covered in “Calling Restrictions” on page 4–44 , which
describes the various ways you can help guard against toll fraud. There are four
additional features you can use to enhance security and make phone use easier
for people in your company:
■ Barrier Codes. Barrier codes are unique passwords assigned to remote
access users. They are designed to prevent unauthorized individuals from
using the system. As noted above, you can also apply calling restrictions to
barrier codes. Change barrier codes frequently and immediately deactivate
any unused barrier codes. In Release 3.1 and later systems (Hybrid/PBX
only), remote access barrier codes are restricted, by default, from making
outside calls.
NOTE:
Read the Security Alert on page 4-67 before using this feature.
■ Disabling Trunk-to-Trunk Transfer. In Release 3.1 and later systems,
extensions are, by default, not allowed to make trunk-to-trunk transfers,
that is, to transfer an outside caller to another outside line/trunk. This
enhancement helps secure against toll fraud. To change the trunk-to-trunk
transfer privileges of an extension, see Chapter 6, “Managing the System.”
■ Star-Code Dialing Pause. In Release 3.1 and later systems, a system
programming feature allows you to help guard against toll fraud when star
codes are dialed under certain circumstances. Star codes, typically dialed
before an outgoing call, provide special services from the CO. For
example, in many areas a telephone user can dial
 before a telephone
number to disable central office-supplied caller identification at the
receiving party’s telephone (to allow or disallow star codes preceding a
call, see Chapter 6, “Managing the System”). Some central offices supply a
