Call Accounting System
NOTE:
CAS is also available as part of the UNIX System-based Integrated Solution H
(IS II) and Integrated Solution Ill (IS Ill) software applications.
CAS runs on an approved DOS PC. Two versions of the product are offered:
CAS for Windows and CAS Plus V3.
HackerTracker System for CAS Plus V3 is a software enhancement designed
to help detect fraudulent use of the communication system. The
HackerTracker software can detect abnormal calling activity by monitoring
facilities and account code usage. It then logs the activity and issues a real-
time alarm.
Considerations
You can connect only one CAS to the system. CAS operates on a dedicated
PC running DOS.
