Free Essays on VOIP

(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 acc...

Free Essays on VOIP INTRODUCTION VOIP means voice over Internet Protocol. A term used in IP telephony to manage the delivery of voice information using the Internet Protocol. It is used to send voice information in digital form in packets rather than using the telephone network. VOIP uses a real-time protocol to help ensure timely and prompt delivery. It also has the potential to change communication and to speed up the delivery of advanced services to all Americans. ADVANTAGES A major advantage of VOIP and Internet telephony is that it avoids the tolls charged by ordinary telephone services. Other advantages include, integration of voice and data, simplification, network efficiency, cost reduction, and many more. The comparison between data and voice network is very similar and the Internet is a huge part for both. The industry trends work over telephone services also. However, the benefits of using IP as a generic platform for both data and real-time application are compelling enough to resolve all issues. MAJOR SYSTEMS A major system component would be the gateways. They are devices that control the communication between the telephone signals and the IP endpoints. It is also an information services that delivers voice communications and joins voice coverage with other data applications and devices. The gateways perform six functions, search function, connection function, digitizing function, demodulation functions, compression function, and decompression and remodulation functions. When the gateway is still performing steps it also receives packets that is where gatekeepers take place. The gatekeeper performs address translation, admissions control, bandwidth management and zone management. An IP telephone is another system component. These devices replace the old telephones by providing enhanced services that are best used for VOIP. QUALITY The voice quality is very important to VOIP technology. There are certain factors tha...
