Voice Over Internet Protocol(Voip)
VOICE OVER INTERNET PROTOCOL (VoIP) INTRODUCTION: In the eyes of most, all packets are created equal. One of the most active areas of telecommunications today is in the area of Voice over Internet Protocol (VoIP). The logic behind this trend makes perfect sense. If we have invested heavily in an Internet Protocol (IP) network, why can’t we make full use of it? This is a question posed by many managers and Information Technology (IT) professionals in a wide range of businesses. Many businesses would prefer to have one network in and out of their business for reasons ranging from cost effectiveness to manageability. IP telephony offers a promise of consolidation. This will allow an enterprise to converge its traditional phone system and newer data network for greater efficiency. Arieh Dranger, president of neXTel Systems LLC says, “I don’t think it’s a question of whether we need VoIP, but when it will come together, because it represents a natural progress of integrating data—period. The IP protocol is probably the most efficient at combining a universal communications network.” Basically, IP telephony is taking the telecom world by storm. It has evolved from a little known and used application in 1995 to an application that is poised for global adoption. But as with all technology, there is a price to be paid, and several entities vying for a piece of the pie. WHAT IS VoIP and HOW DOES IT WORK? To put it simply, VoIP means Voice over Internet Protocol. It’s a technology that allows network managers to route phone call over the network they use for data transmission. A voice travels over a corporate Intranet or the Internet instead of the public telephone system. Special gateways installed at both the sending and receiving end of a communications channel converts voice to IP packets and back again to voice. This process must take place in a time frame of less than 100 milliseconds to sustain the Quality of Service (QoS) that users are accustomed to from the Public Switched Telephone Network (PSTN). Now let’s take a walk on the more detailed side of what VoIP is and how it works. First and foremost, VoIP is an emerging technology still in the early stages. A personal computer (PC) must capture an analog voice and convert it to a digital signal, compress the audio with a compression-decompression (codec) device and then move...

...the Internet. The players are as equally far flung, from the traditional cornerstones of the Plain Old Telephone System (POTS) to the new generation startups, to the steps of local, state, and federal governmental agencies. Such dynamism makes it difficult for IT managers to filter the flood of information and assess how VoIP might fit into their networks. Unless PSTN undergoes some massive restructuring, its long-term existence in its current form is in serious doubt. Emerging Internet technologies will be the low cost solution for managers looking for mixed traffic connectivity. Only in the end, after all the smoke has cleared will we know which business models survived the shake down in this lucrative market. Other problems are bound to arise in the arenas of technology and regulation. At this point there is significant progress to be made in the area of VoIP to achieve the quality we enjoy today with the PSTN. The only sure thing from this technology or any other that will always be consistent, reliable and never become outdated is that the Government WILL find a way to ensure their revenue stream… after all “There’s no such thing as a free lunch.”

Of particular importance is the deregulation of the telecommunications industry as mentioned in the act (“Implementation of the Telecommunications Act,” NTLA). This reflects a new thinking that service providers should not be limited by artificial and now antique regulatory categories but should be permitted to compete with each other in a robust marketplace that contains many diverse participants. Moreover the Act is evidence of governmental commitment to make sure that all citizens have access to advanced communication services at affordable prices through its “universal service” provisions even as competitive markets for the telecommunications industry expand. Prior to passage of this new Act, U.S. federal and state laws and a judicially established consent decree allowed some competition for certain services, most notably among long distance carriers. Universal service for basic telephony was a national objective, but one developed and shaped through federal and state regulations and case law (“Telecommunications Act of 1996,” Technology Law). The goal of universal service was referred to only in general terms in the Communications Act of 1934, the nation's basic telecommunications statute. The Telecommunications Act of 1996 among other things: (i) opens up competition by local telephone companies, long distance providers, and cable companies ...
Years later, the Telecommunication Act of 1996 triggered dramatic changes in the competitive landscape. SBC Communications Inc. established itself as a global communications provider by acquiring Pacific Telesis Group and becoming the new AT&T. The merger of AT& T and BellSouth, along with the ownership consolidation of Cingular Wireless and YELLOWPAGES.COM, will speed convergence, competition and continued innovation in the communications and entertainment industry, creating new solutions for consumers and businesses and positioned to lead the industry in one of its most signifi...
The world is experiencing a communications revolution. The Internet, e-Commerce and other developments (including the convergence of communication technologies) are profoundly reshaping economic and social life. AT&T must position itself to meet the challenge of this revolution. The strategic development of information-based industries is a key to the future social and economic development of the world.
The history of the internet takes us back to the pioneering of the network and the development of capable technologies. The explosion of the internet’s popularity of the 1990’s was large and dramatic, boosting our economy and then helped to bring it into a major recession. One can only hope that the explosion becomes organized and slightly standardized in the interest of the general public. Despite all of these conjectures and speculations only time can tell the future of the largest network in the world.
The research for this report consisted of case studies of two commercial deployments of residential Internet access, each introduced in the spring of 1994:
Background One. Tel was launched by Jodee Rich and Brad Keeling in 1995 (Cook, 2001). At first, it looked to get the advantages from deregulation of the telecommunication industry by reselling other network’s capacity and making money through stock market speculation. Rich and Keeling tried to increase the company’s shares rather than profit the company (Cook, 2001). Initially, One.
The main advantage of using this system is that is supports voice over IP (VoIP) services such as IP-Centrex. IP Centrex is a service that provides a single broadband access point to a company. The company can use this access point to broadcast packets of voice data. When no voice data is present, more bandwidth is available to other uses of the company. This results in saved money to the company because dedicated phone lines are not needed.
Telecommunication in today's business world is constantly growing and continues to be considered as a major asset to the business world. It is crucial for a company to have a better understanding of all of the available and up-to-date technology. The businesses should also be capable of conducting an effective communication relationship among the company. These important elements are a multicultural workforce within a large company, diverse cultures and how they can work together, communication barriers among the employees, and financial benefits of having a diverse and multicultural workforce. For the success and growth of any company currently, these companies need to be familiar with the daily changes of modern technology and be able to adapt with these changes.

Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
While some consider telephony to be restricted to voice services, common usage today includes all services that have been using the telephone network in the recent past, such as modems, TTY, facsimile, application sharing, whiteboards and text messaging. This usage is particularly appropriate for IP telephony, since one of the strengths of Internet telephony
When electronic devices transfer information to another electronic device, the devices need to know when data flow is beginning and ending. This is done with signals for synchronization.i
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make regular telephone calls using a dial up or broadband internet connection instead of a regular phone line. Some services using VoIP may only allow you to call other people using the same service, bu...
