In this paper we researched on the implementation of the B-ISDN protocol embedded Internet-Phone PBX System for the previous telephone exchange and communication. We suggested implementation methods of the Internet-Phone PBX System, designed the structure of the user terminal and exchange server, designed call control message flows for user's communication and showed core programming codes for the system implementation.
