Abstract
Unlike many common media gateways that simply exchange audio packets between senders and receivers, our AGW introduced here can work in heterogenous network environments and support an adaptive receiver-based audio transmitting stategy. Before relaying audio packets from source to destination, it decodes and analyzes the source packets, performing Automatic Gain Control (AGC) and Voice Automatic Detection (VAD) to enhance audio quality. And then it individually mixes audio data according to receivers’ requirements, inserting additional useful paddings and sending them out in different codecs. It has been proved that this method can help our system to serve large amounts of clients easily.
