Patent ID: 7664646

Claim:
A computer readable medium containing instructions for controlling a computing device to provide background sound processing during an ongoing call, the instructions comprising: receiving an input voice signal and a background noise signal by an access gateway and converting the input noise signal into a packetized voice signal and a packetized noise signal; transmitting the packetized voice signal and the packetized noise signal from the access gateway to an egress gateway via a network; receiving the packetized voice signal and the packetized noise signal by the egress gateway and converting the packetized voice signal into an output voice signal; extracting and storing by the egress gateway noise packets from the received packetized noise signal and converting the packetized noise signal into an output noise signal; and upon ceasing to receive the input voice signal by the access gateway while the call is still ongoing, instructing the egress gateway to continually output the output noise signal.
