VoIP(Voice over IP), so called Internet phone, provides several unique advantages, for instance, inexpensive long distance call service than the existing wire telephone network and various multimedia services from Internet network added to voice call service. This has been widely discussed and has been a research topic throughout the developed countries in the recent years. The paper is intended to describe and analyze the feasibility of the results of the VoIP system designed if implemented in a campus network like Dhaka University telephone network. Thus the convergence strategy of an IP PABX system with the existing wire telephone network has been discussed.
