Protecting passwords
The AUDIX Voice Power System offers password protection to help restrict
unauthorized access. Subscribers should use a maximum length password and
should change it routinely. Passwords can be up to 9 digits. See ‘‘Administration /
maintenance access’’ on page 4-4 and ‘‘General security measures’’ on page 4-8
for secure password guidelines. See Chapter 14
for information on how to change
passwords.
Security tips
The following security measures assist you in managing features of the AUDIX
Voice Power System to help prevent unauthorized use.
■ Set Transfer to Subscribers Only to yes. This limits transfers to
only those switch extensions with a mailbox in the AUDIX Voice Power
System.
■ Require employees who have voice mailboxes to use passwords to protect
their mailboxes. See ‘‘Administration / maintenance access’’ on page 4-4
and ‘‘General security measures’’ on page 4-8
for secure password
guidelines.
■ Make sure subscribers change the default password the first time they log
in to the AUDIX Voice Power System.
■ Have the AUDIX Voice Power System administrator delete unneeded voice
mailboxes from the system immediately.
■ On the System Parameters screen, use the maximum number of digits
allowable for extension entry (six). This will make it more difficult for
criminals to guess the login and password combinations of your users.
■ Set up automated attendant selection codes so that they do not permit
outside line selection.
■ If you have Release 1.0 of the AUDIX Voice Power System, implement all
appropriate security measures on the PBX side.
■ If you do not need to use the Outcalling feature of the AUDIX Voice Power
System, completely restrict the outward calling capability of the AUDIX
Voice Power System ports through the COR assignments of the ports on
the switch.
■ If outcalling is used, restrict the calling area through the CORs of the voice
ports on the switch.
!
WARNING:
Entering “#” transfers calls to the switch; that is, the transfer feature is
always available and appropriate outgoing port restrictions must be in place
to avoid toll fraud.
