Abstract: The present invention is a system and method for packetizing actual noise signals, typically background noise, received by an access gateway from a speaking party and transmitting these packetized noise signals via a network to an egress gateway. The egress gateway converts the packetized noise signal into noise signals suitable for output and transmits the output noise signals to a listening party. When the access gateway detects that no voice signal is being received and only a noise signal is being received for a predetermined period of time, the access gateway instructs the egress network to continually transmit output noise signals to the listening party and ceases to transmit packetized noise signals to the egress gateway.

Abstract: The present invention is a system and method that improves upon voice activity detection by packetizing actual noise signals, typically background noise. In accordance with the present invention an access network receives an input voice signal (including noise) and converts the input voice signal into a packetized voice signal. The packetized voice signal is transmitted via a network to an egress network. The egress network receives the packetized voice signal, converts the packetized voice signal into an output voice signal, and outputs the output voice signal. The egress network also extracts and stores noise packets from the received packetized voice signal and converts the packetized noise signal into an output noise signal. When the access network ceases to receive the input voice signal while the call is still ongoing, the access network instructs the egress network to continually output the output noise signal.

Abstract: The quality of conversational voice for Voice-over-Packet transmissions on a Path (11) in a packet network (10) is achieved by injecting probe packets for transmission along the path and then measuring packet loss and the delay. From the delay and loss measurements, analytic values for the voice quality impairment caused by delay and by network loss, respectively, are established. An overall measure of the conversational voice quality is then derived in accordance with the algebraic sum of the analytic values for the voice quality impairment caused by delay and by network loss, respectively.

Abstract: The present invention provides a method of transmitting a data signal across an intermediate network. The intermediate network receives a compression control signal associated with the data signal that provides information about the compression format of the data signal. The intermediate network uses this information to determine whether and where to transcode the data signal within the intermediate network. The data signal is then transmitted across the intermediate network, and transcoded as determined.
