| Abstract: | The of VoIP（Voice over IP） technology is studied, the technical principle of VoIP analyzed, and the advantage-and-disadvantage comparison of ITU-U＇H.323 and IETF＇ SIP done. Based on these and in accordance with the development of In-vehicle voice communication system a design scheme based on VoIP（Voiee over IP） is proposed. The system architecture, the reference design for voice integrated access equipment is given, thus providing a new thought for muhi-service access application of in-vehicle voice communication system. |
