You can use a single voice-mail system to support multiple servers running Communication Manager in a
DCS network. In addition, you can use a voice-mail system to support multiple Communication Manager
servers and Merlin Legend in a network via mode code. For more information, see Administration for
Network Connectivity for Avaya Communication Manager.
Security Measures
!
SECURITY ALERT:
Fraudulent long-distance calls can be placed through INTUITY AUDIX, embedded
AUDIX, and AUDIX R1 if proper security precautions are not implemented.
The following actions help secure your system from unauthorized use.
•
For INTUITY AUDIX, embedded AUDIX, and AUDIX R1
— Remove any unused or unassigned mail to help prevent exchange of information through
unassigned Voice Mail.
— Secure system lines that serve AUDIX and control where calls can be placed.
— Assign a restrictive COR, COS, and FRL to the station lines and trunks serving AUDIX.
— Use CDR reports in Communication Manager to determine if the lines are being used for
calls that are normally not within your sphere of business.
— Change default passwords on voice mailboxes immediately after installation and use
random numbers for passwords.
— Require passwords with at least 5 digits.
— Change system administration passwords to alphanumeric codes.
— INTUITY AUDIX, AUDIX R1, and embedded AUDIX provide a
maintenance/administration port. A remote port security device provides an added layer of
security to prevent unauthorized access to this port.
•
For INTUITY AUDIX and embedded AUDIX
— Determine whether to only allow transfers to other AUDIX subscribers or to any
extension of the correct length. The most secure approach is to only allow transfers to
other AUDIX subscribers. If you decide to allow transfers to any extension, administer the
COR on the AUDIX ports to prevent calls outside the PBX or immediate Distributed
Communications System (DCS) site network.
