基于OMAP5912和SIP的IP电话终端

IP Phone Terminal Based on OMAP5912 and SIP

以车载汽车电子多媒体视听系统为研发背景,在OMAP5912平台上采用SIP(会话发起协议)设计了IP电话终端。详细说明了IP电话终端的主要硬件组成部分,介绍了SIP和oSIP协议桟,给出了嵌入式系统IP电话软件的程序设计框架和效果,并对在该基础上实现无线IP电话终端提出了进一步的设想。

This paper introduces the design of IP Phone terminal using SIP （Session Initiation Protocol） upon the OMAP5912 platform of a vehicle electronic multi-media video and audio system. Detailed instruction of main hardware components is presented. The software architecture and final effect of the IP Phone are shown with the instruction of SIP and oSIP stack. Finally, this paper discusses the application of wireless IP Phone terminal in embedded system.
