Conceived, designed, built and programmed an advertiser- supported long-distance telephone system. The system contained switching and messaging hardware and software that enabled advertisers to provide free switched telephone service and to both target and track delivery of advertising impressions to individual callers. The system was capable of collecting caller responses using touch tones and voice recording and was able to be customized by the advertiser or operator without reprogramming. The software consisted of a real-time C language module controlling the operation of the telephone system plus a C language database for call and message accounting and delivery.
