Speech compression and real-time transmission control technology continues to evolve, making the Internet to transmit voice data in the ip is no longer difficult, ip phone successfully entered the telecommunications network. This paper reviews the concept of IP telephony, the development process and the status quo, not in time for the traditional phone is not convenient, the use of the Internet and the global IP interconnection environment and provide more than traditional business, better service. VoIP can be cheaper in the IP network to send voice, fax, video, and data services such as unified messaging, virtual phone, virtual voice, fax, mail, check number service, Internet call centers, Internet call management, video conferencing, electronic Business, fax store and forward, and various information such as store and forward. Application of speech coding, echo cancellation, voice processing technology to achieve jitter from the IP network to transmit voice purposes. Have to make better use of existing internet resources, to provide users with more and better quality of service features. Among them, IP-based voice communications network for people to provide a long-distance exchange of low-cost way to end the current exchange in the traditional areas of dominance. VoIP can be cheaper in the IP network to send voice, fax, video, and data services such as unified messaging, virtual phone, virtual voice, fax, mail, check number service, Internet call centers, Internet call management, video conferencing, electronic Business, fax store and forward, and various information such as store and forward. Keywords: Network IP Network architecture Network program development Trend of key technologies
