Abstract Ever tried placing a voice call over the Internet ? If you have, we are sure you a pleasant experience. You might have even promised yourself haven’t had never to try it again. But , Stop right there!! Now get ready to change your mind. In the near future, if you make a telephone call, it is more than likely that it would be over the Internet or some other packet network. But, what is it that would make this possible? It is a bunch of protocols and standards; and years of research done by organizations all over the world that would bring about this revolution. They call it OVER ‘VOICE IP’, & a host of other names. VoIP (voice over IP - ‘INTERNET TELEPHONY’ that is, voice delivered using the Internet Protocol) is a term used in IP telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP). In general, this means sending voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public switched telephone network (PSTN). A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service. VoIP is therefore telephony using a packet based network instead of the PSTN (circuit switched). With the passes of time VoIP replace the PSTN and people will acquaint with which will reduce their cost and they will no more inclined the new technology to the PSTN to make a call anywhere. Somehow it will take time to replace the communication system invented by Bell.
