VOIP(VoiceOverIP)是利用IP网路作为传输载体来实现语音通信的技术.语音网关GateWay(简称GW)位于公用电信网PSTN和网络接入站点之间,采集来自PSTN网络上的模拟语音信号,转换成为数字信号,进行压缩编码,然后通过网络传送到对端语音网关,同时接收来自于网络上的分组语音IP包,解压后,通过数模转换,还原成PSTN网络的模拟语音信号,在路由器上实现VOIP电话功能,实际上是对路由器功能的扩展,同时这也代表着数据业务向语音业务逐步扩展的趋势。IPv6基本报头

(VOIP (VoiceOverIP) is a technology that uses IP network as a transmission carrier to realize voice communication. The voice gateway GateWay (GW for short) is located between the public telecommunication network PSTN and the network access site, collects analog voice signals from the PSTN network, converts It becomes a digital signal, compresses and encodes it, and then transmits it to the peer voice gateway through the network. At the same time, it receives the packet voice IP packets from the network. After decompression, it is converted into an analog voice signal of the PSTN network through digital-to-analog conversion. On the router The realization of the VOIP telephone function is actually an expansion of the router function, and it also represents the gradual expansion of the data service to the voice service.
