摘　　要：实现了一款嵌入式语音通信终端。该终端硬件系统采用飞凌嵌入式开发板OK6410,其核心板采用以ARM11为内核的处理器S3C6410。该终端软件部分基于嵌入式WINCE操作系统,实现了基于SIP协议的LINPHONE代码的移植和分析。首先,分析了所涉及语音通信终端的硬件和软件架构;其次,重点对LINPHONE的工作流程和SIP协议进行了分析;最后,通过测试表明该终端系统具有良好的话音通信质量。An embedded voice terminal system was achieved. The hardware of the terminal system uses a Felling embed ded development board OK6410. Its core board employs S3C6410 processor which takes ARM11 as the kernel. The software of the terminal system uses embedded WINCE operating system and achieves the transplant of I,INPHONE code based on SIP protocol. This paper analyzed the architecture of the entire VOIP voice system including hardware and software. Then,we focused on the analysis of LINPHONE work process and SIP protocols. Finally, the test shows that this system has good voice communication quality.
