| Abstract: | To present a VoIP-based solution to LAN/Intranet-oriented IP Phone. Its core is low power dissipation DSP chip incharge of voice codec and 8/16bit single-chip in charge ofcommunications protocol processing and control logic. This IPPhone can be used either as a desktop PC peripheral or as anInternet network terminal by R J45 or other interfaces. This pa-per introduces VoIP technology and H.323 protocol stack, andsome details of hardware design architecture are discussed yet. |
