VOIP : Voice Over Internet Protocol

Abstract:(Seminar) Although Voice over IP (VoIP) has existed for several years, it has only recently begun to take off as a viable alternative to traditional public switched telephone networks (PSTN). Interest in VoIP has grown in part because the technology can help organizations reduce costs by using a single IP network to support both data and voice applications. But cost is not the only factor driving VoIP’s growth. Service providers are also attracted by VoIP’s revenue potential. Operators can use their VoIP networks to rapidly deploy new value-added and high-margin applications and services. Organizations can choose from a variety of equipment and networking protocols to implement their VoIP solution. Just as in data networking, identifying the appropriate equipment and technology for the VoIP network depends heavily on an organization’s business and technical requirements. This paper describes the basic networking functions, components, and signaling protocols in VoIP networks. It explores the ramifications of deploying VoIP as well as the service considerations that drive specific equipment and technology choices. This paper is intended to provide organizations with a general understanding of VoIP, so that they will be better prepared to solve the more complex issues associated with deploying a secure and assured VoIP network. VoIP (or Internet telephony which is almost the same thing) is any one of everal technologies that allow you to make phone calls over the Internet instead of over the telephone network. Some more advanced and secure systems use a private data network instead of the Internet. This technology has been around since the 1970s but hasn't been practical until recently because for it to be effective you need a broadband/high-speed connection. Specifically you need a bit more than 100kbps per connection using modern VoIP transmission technologies. This has only recently become common among residential broadband subscribers.
