Interactive system for responding to conditions after an answering machine has been detected in an automatic telephone number dialer system so that realistic sounding recorded messages can be delivered in their entirety within three seconds of an answering machine starting to record so that the message is delivered without truncation onto the answering machines recorder. The system accurately predicts when the connected answering machine begins recording. The system has a two tier approach which takes place after the system has already determined it has connected to an answering machine. In the first tier, the system monitors for one of two conditions which indicates that recording is about to begin. The first tier threshold is met when either a solid non human tone lasts at least one second in duration, or when there is silence for at least two seconds in duration. The second tier threshold has the system continue to analyze the call until a silence condition has been met. Once there is confirmation of silence the answering machine starts recording for a selected time period which depends upon the first tier. The system can work with all types of answering machines such as a tape …
