Abstract: The design of a CDMA based wireless IP Phone terminal using SIP (session initiation protocol) upon the OMAP5912 platform was discussed, under the background of a vehicle electronic multimedia video and audio system. The hardware designation plan of wireless IP phone terminal was firstly presented, and then the program architecture was also shown after analyzing SIP and oSIP stack. Finally, the IP phone terminal was implemented and the test result was presented, upon OMAP5912 platform and MontaVista Linux system embedded with the combination of the plan that was presented. Also, the plan itself was compared with other mobile terminals.
