 Set up auto attendant selection codes so that they do not permit outside
line selection.
 Assign toll restriction levels to the AUDIX Voice Power System ports.
 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.
!
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.
Security Measures
The security measures described in this section do not apply if you are using
Release 1.0 of the AUDIX Voice Power System. In this case, use switch
restrictions.
Transfer Only to System Subscribers
The AUDIX Voice Power System has the ability to allow callers to transfer only to
mailbox subscribers. When an AUDIX Voice Power System caller requests a
transfer using *T followed by an extension number, the AUDIX Voice Power
System can compare the extension number entered with the valid extension
numbers administered in the subscriber database.
If the extension is invalid, the transfer is denied and an error message is played to
the caller. However, it does not prevent transfers from pre-administered dial
strings in the automated attendant from accessing the outgoing facilities. Refer to
Chapter 7 for procedures to restrict the automated attendant ports.
 On the AUDIX Voice Power System, within the System Parameter
Administration form, enter
yes in the Transfer to Subscribers Only field.
NOTE:
You cannot use this security measure if calls are transferred to
people in your company who are not AUDIX Voice Power System
subscribers (see ‘‘Limit Transfers Out of the System’’ on page 6-31).
Limit Transfers Out of the System
When you need to allow transfers to people who are not AUDIX Voice Power
System subscribers, you can add their extension numbers to the AUDIX Voice
Power System subscriber database, but restrict access to their voice mailboxes.
 On the System Parameter Administration form, enter yes in the Transfer to
Subscriber Only field.
 On the Subscriber Administration form, add each extension number for
non-AUDIX Voice Power System subscribers.
