摘　　要：近年来,多媒体通信技术发展迅速,SIP协议得到了广泛应用。IP电话自问世以来,由于其低廉的通话费用,高智能化及较高的通话质量等特点,受到了人们的广泛关注,给传统通话技术带来了严峻挑战。主要对嵌入式linux平台下VOIP终端的实现进行了研究,着重讨论了嵌入式PJSIP协议栈的移植、软终端的实现,以及图形用户界面(GUI)的设计。Recently,technology of multimedia communication developing rapidly,SIP protocol is widespread used.Since Internet Protocol phone advent,because the less cost of phone call,high intelligent,nice tone quality and etc,IP phone has caused wide public concern,but has also brought formidable challenges to the traditional communication techniques.Primary research the implementation of the VOIP terminal under embedded linux platform,and emphasize the porting of the embedded PJSIP protocol,the implementation of the softphone,as well as the design of the graphical user interface.
