7-40 Issue 9 May 2003
■ Set up automated 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 8
 for procedures to restrict the automated attendant ports.
■ On the AUDIX Voice Power System, within the System Parameter 
Administration screen, 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 7-32
).
