Abstract: To implement voice service over packet-based network (Internet) and TDM-based network (PSTN Public Switched Telephone Network), an IP phone gateway is necessary to transform media stream and convert signaling protocols used over both the two networks. In this article, the architecture of the IP-Phone gateway is described firstly. Then the communications mechanism between functional blocks and multi-thread consideration are presented.
