摘　　要：目的:为解决以往视频会议系统的弊端,设计基于信令控制协议(session initiation protocol,SIP)的远程医疗会议系统。方法:利用网络地址转换(network address transkation,NAT)穿透技术,采用SIP服务器,利用相应的SIP会议模型、互联网,实现专家与患者间的零距离诊断。结果:该系统在视频会议的过程中,通话质量、视频的清晰度与流畅度、音视频的同步基本可以满足实际的需求。结论:该系统可以实现远程医疗通信,及时高效地为患者提供专家级的服务,有助于提高医疗效率。Objective To develop a telemedicine conferencing system based on session initiation protocol（SIP）. Methods The system realized zero-distance diagnosis with network address transkation technology, SIP server, SIP meeting model and internet. Results The system met the desired requirements in speaking quality, video clarity and fluency as well synchronization between voice and video. Conclusion The system implements remote medical communication and enables the patient obtain access to expert service.
