ABSTRACT:
A telephone nuisance call mitigation device operates in conjunction with an answering machine. The usual ringer of the user's telephone(s) is deactivated. The answering maching produces a message which instructs the user to enter his secret code if he has it or else just to leave a message after the tone. The mitigation device monitors for the proper secret code being entered, and if received produces an off hook and a ringing tone in the user's home for a predetermined period. Otherwise, the user can only leave a message, and a ringing tone will never be provided to the user's house. Provision is also made for preventing erroneous detections during call out operations, and for resetting the system to maintain synchronization. The mitigation device is continuously parallel to the telephone line.
