ABSTRACT:
Apparatus and method to provide enhanced wide area audio response services through an enhanced wide area audio response network which includes a central controller and a plurality of audio peripherals distributed over a wide area, each audio peripheral being connected to telephone lines for receiving and originating telephone calls, converting received analog audio signals into digital representations, recording and storing digital representations, converting stored digital representations into analog audio signals, playing audio signals over connected telephone lines, and communicating with, including receiving commands from, the central controller over a Packet Switched Public Data Network (PSPDN), which controller is a highly reliable general purpose controller which offers utility grade service to each audio peripheral and utilizes Dialed Number Identification Service (DNIS) tables for various applications, including voice messaging, audio text, remote information provider accessing, and testing to provide error notification.
