Abstract: An embedded voice terminal system was achieved.The hardware of the terminal system uses a Feiling embedded 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 LINPHONE 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.

Key words: VoIP,WINCE,LINPHONE,SIP,ARM11 platform,Asterisk
