Now is the age of information technology. World is advancing day by day. At present in this progressing world communication from one place to another has become so easy, less costly, and faster. This modern life is almost impossible with the help of these communication technologies. People need to talk, need to share data, need to express their emotion from long distance. So they need to use technologies to communicate with one another. Some software like Skype, Yahoo, Gtalk, and Msn is used for this purpose. But these software uses high capacity of bandwidth and a big amount of internet speed. Thinking of this, I propose a Secured Portable PABX System for Fully Fledged Mobility Management of Unified Communication that operates with local LAN bandwidth consist of three limited equipments-1) Server 2) Soft phone 3) Web cam. With this system people can make video call using low internet speed. It has unique extension number that gives access to the parties within a communicating session. It is possible to make video call through this system with lower cost and lower internet speed independent on operating system. The main advantage of this system is the portability of the system. It can run on both Linux and Windows operating system that makes it special. This system can be implemented on telecommunication sectors like call center, mobile phone customer care center etc. It also implemented in security issue like CCTV camera. Finally, this system is better because it has the ability to make calls in different extensions also has the ability to show video calling with conferencing, web conferencing and presentation articles at a time within a conference session.
