Abstract

This project consists of the design and construction of a device which prevents receipt of unwanted telephone calls. This system can be connected to the user's existing equipment (i.e. telephone and answering machine). When a call is received, this device will answer and prompt the caller for a code. If the code entered matches the one set by the user, this device will ring the attached telephone. If the code entered does not match, this device will connect to the attached answering machine.
