Abstract
This article presents an implementation of PSTN media gateway. The architecture of media gateway and the media processing scheme are described. It´s designed from the idea of decomposed gateway. SIP, as a new VoIP technology, is adopted as the signaling protocol in the NGN. In the scheme we present the architecture of the hardware, the software control modules, and some other kernel technologies used in the media gateway.
