| Abstract: | To present a VoIP-based solution to LAN/Intranet-oriented IP Phone.Its core is low power dissipation DSP chip in charge of voice codec and8/16bit single-chip in charge of communications protocol processing and control logic.This IP Phone can be used either as a desktop PC peripheral or as an Internet network terminal by RJ45or other interfaces.This pa-per introduces VoIP technology and H.323protocol stack,and some details of hardware design architecture are discussed yet. |
