A PC based voice mailing system

The design and development of an IBM PC/AT-based low-cost voice mailing system (VMS) is described. This system, targeted for small to medium organizations, can receive and store incoming telephonic messages. The called party can later use an ordinary touch tone telephone to access his own private area on the system and do operations like playing back or deleting messages. The VMS consists of cards that can be plugged into the PC/AT bus slots and master software running on the PC/AT under the OS/2 operating system. In its maximum configuration, the system can simultaneously handle four subscriber lines from an EPABX and is estimated to support around 150 users.<
