Abstract
Using embedded chip to develop VoIP device not only can reduce production cost of VoIP application device and its maintenance cost effectively,but also can promote application of VoIP,which makes it access network more flexibly and conveniently.The paper introduced the basic principle of VoIP,expounded hardware composition and software design of the VoIP terminal taking Intel IXP425 as core,gave the work how to transplant embedded Linux system to the VoIP terminal,finally it tested the performance of the embedded VoIP terminal based on Intel IXP425.The test result showed that the terminal can provide perfect function,friendly and direct operation interface,better voice quality and lower power consumption,and has high feasibility and expansibility.
