  • Patent number: 4241238
    Abstract: A telephone number memory and indicator system which allows a caller to leave his number when the person to whom he is calling is absent. The system includes an automatic answering system which detects a ringing signal and intercepts the call after a predetermined time. On interception a proceed signal is generated by generator which indicates to the caller, or to elements within his telephone, that the system is ready to receive his number data. This data when transmitted is detected by detectors within the system and stored in store for future recall.
