基于AudioCodes芯片的语音网关驱动设计与实现

Media-Gateway, which connects the IP networks and PSTN, plays an important role in the VoIP resolutions.Media-Gateway can work like a terminal of the PSTN, taking part in calling process just like a telephone, and it also can perform like a IP telephone. The driver program is an important part of the software system of Media-Gateway, and it determines the Gateway’s process power、expansive ablity and reliability. In this paper, the hardware and software structure of the Media-Gateway will be introduced, and then is the design of the driver program and the realization of the main processes.
