Systems and methods for implementing internet video conferencing using standard phone calls
Abstract:
A video conferencing system (100) includes a switch (125), a server (140), a telephony device (152), and a node (102) in a packet-switched network (135). The switch (125) establishes a circuit-switched connection between a calling party number and a called party number. The server (140) associates first and second network addresses in a packet-switched network (135) with each of the called party and calling party numbers. The telephony device (152) transmits audio data via the circuit-switched connection. The node (102) in the packet-switched network (135) transmits packetized video between the first and second network addresses responsive to establishment of the circuit-switched connection.
Abstract(Chinese):

视频会议系统（100）包括交换机（125），服务器（140），电话设备（152）和分组交换网络（135）中的节点（102）。 交换机（125）建立主叫方号码和被叫方号码之间的电路交换连接。 服务器（140）将分组交换网络（135）中的第一和第二网络地址与被叫方和主叫方号码中的每一个相关联。 电话设备（152）经由电路交换连接发送音频数据。 响应于电路交换连接的建立，分组交换网络（135）中的节点（102）在第一和第二网络地址之间发送分组化视频。
