摘要：Working people employee the use of technology in such very effective natural ways that permit them to do what they want: they can communicate with anyone as per need, in the time and space that suits them the best. Easily accessible and user-friendly, collaboration tools allow them to explore, share, engage, and connect with people and content in meaningful ways that help them learn. Traditional telephony carriers use circuit switching for carrying voice traffic. Circuit switching was designed for voice from the outset; hence it carries voice in an efficient manner. However it is an expensive solution. Nowadays people want to talk much more on phone, but they also want to communicate in a myriad of other ways - through e-mail, instant messaging, video, the World Wide Web, etc. Circuit switching is not suitable for this new world of multimedia communication. Therefore, in this paper a solution is proposed to implement scalable VOIP system over Fatima Jinnah University that will lead to better Quality of service and facilitates enhanced communication
