Outgoing Voice Call Detail Record
(AUDIX Voice Mail System Only)
An outgoing call record is also created for every outbound call that is originated by
the AUDIX Voice Mail System via a voice port. This includes call transfers,
outcalling, and message waiting activation and/or deactivation via access codes.
A record is also created for call attempts for the Message Delivery feature.
The outgoing voice call detail record supplies the date the call was placed, the
time, the AUDIX Voice Mail System port number used for the call, the duration of
the call, the voice mailbox id, the number dialed, and the call type as shown in
Table 6-5.
Unsuccessful call transfer attempts can result in multiple records being created for
a single session. Review these records regularly for the following signs of hacker
activity:
 Failed login attempts
 Multiple call transfers for a single session
 Numerous outbound calls from the same voice mailbox
 Calls to strange places
 Heavy volume of Transfer Out of AUDIX Voice Mail System calls
