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 all over Internet Protocol (VoIP). The logic git this trend makes perfect sense. If we have invested heavily in an Internet Protocol (IP) network, why cant we make full use of it? This is a chief 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 forget al downcast an enterprise to converge its traditional phone transcription and newer data network for greater efficiency. Arieh Dranger, president of neXTel Systems LLC says, I dont think its a question of whether we need VoIP, but when it will pose together, because it represen ts a natural progress of integrating dataperiod. 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 international 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. Its a technology that allows network managers to route phone call over the network they use for data transmission. A vocalization 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 business line 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 take the Quality of Service (QoS) that users are accustomed to from the Public Switched Telephone Network (PSTN). Now lets take a walk on the to a greater extent 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 middle-aged 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 skill 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 sol ution for managers looking for mixed traffic connectivity. Only in the end, afterward all the smoke has cleared will we know which business models survived the trill 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 Theres no such thing as a free lunch. 6 pagesWord Count 2352
