Automatic remote communication using network telephony

摘要

The present invention is a method and apparatus to provide remote communication using network telephony. In a transmitter, an activation message is decoded to generate an activation command. The activation message is sent from an activator via a communication medium in response to a telephony call. An information message is transmitted, responsive to the activation command, to a receiver using a communication protocol. In a receiver, an activation message is decoded to generate an activation command. The activation message is sent in response to a telephone call. An information message is received, responsive to the activation command. The information message is sent from a transmitter according to a communication protocol via a communication medium.
