Implementation of Secured Portable PABX System of Fully Fledged Mobility Management for Unified Communication

Résumé

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.
