Patent ID: 7230955

Claim:
A silence suppression system, comprising: an access gateway, wherein the access gateway receives an input voice signal and converts the input voice signal into a packetized voice signal, receives an input noise signal and converts the input noise signal into a packetized noise signal, and includes an access silence suppressor; a network over which the packetized voice signal and packetized noise signal are transmitted; and an egress gateway, wherein the egress gateway receives the packetized voice signal and converts the packetized voice signal into an output voice signal and outputs the output voice signal, receives the packetized noise signal and converts the packetized noise signal into an output noise signal and outputs the output noise signal, and includes an egress silence suppressor, wherein when the access gateway continually receives the input noise signal, the access gateway ceases to transmit the packetized noise signal through the network and instructs the egress gateway to continually output the output noise signal.
