This section is intended solely as an overview of the application. For
comprehensive information about the use of the application, see the
documentation for the product.
CAS is a software application for businesses that need to manage telephone
usage and control costs by tracking, sorting, and recovering telephone
charges. CAS provides a menu-driven user interface and on-line help.
There are three versions of CAS:
CAS integrated with IS Ill
CAS Plus V3 for general business use, a standalone application that
runs on an approved AT&T DOS personal computer (PC)
CAS/Hospitality (CAS/H) for hotels and health care facilities, a
standalone application that runs on an approved AT&T DOS PC
All three versions allow businesses to calculate the cost of calls by using the
rates charged by long-distance carriers in one of 11 major metropolitan areas.
In addition, CAS Plus V3 and CAS—IS Ill can be customized by programming
additional rate tables.
CAS Plus V3, CAS/H, and CAS—IS Ill provide the following services and
features:
Call Record Processing— records of calls are collected and stored, and
costs are calculated using the rate table selected. The system can be
programmed to process all calls or only calls that exceed a specified
cost threshold. It can also add a service charge to calls before billing
them to clients, departments, projects, or (with CAS/H) rooms.
In addition, CAS-IS III collects and processes automatic number
identification (ANI) information (caller identification), and can provide
detailed information on incoming calls by point of origin. However, the
availability of this information may be limited, depending on the legal
jurisdiction and the equipment at the telephone company central office
(CO) serving the caller.
