AUTOMATED SYSTEM FOR ESTABLISHING TELEPHONE VOICE CONNECTIONS

摘要

To provide plural, automatic dial-up telephone voice connections, a computer (22a) contains a data base of potential call recipients and is associated with an EIA RS-232 Data Communication Equipment interface which drives an auto-call unit or dialer (30) through a format conversion device (36) compatible with a dialer EIA RS-366 automatic calling equipment interface. A line signalling device (32) monitors the dial digit stream for paired-receivers voice connection commands and establishes under control of the computer a voice connection between an external or remote station (via 14b) and an internal or local extension (16a) upon receipt of such commands. The computer then disengages itself from the connection, which is maintained. While a previously established voice connection may continue to be in progress, the computer is free to process a new sequence of dial digits from the data base to establish a voice connection between a next successive pair of receivers in an automated, high-speed repetitive manner.
