A History of Voip

Using VoIP (Voice over IP) is rapidly increasing from year to year. It is expected that by the end of 2009 there will be 256 million users of VoIP worldwide. The benefits of VoIP in terms of scale, cost and easy to use are now commonly accepted. But where did VoIP start? Who invented the VOIP? The history of VoIP extends further into the world of the Internet before most people think. The first VoIP calls where made as far back as 1973. The ability to send voice data over a digital network has been launched on the ARPANET, the forerunner of the modern Internet. He carried only voice and data between the private network of computers on the network APRPANET but the seeds of revolution sown by VOIP where these pioneers. Voip continued to develop in a small cache of computer users who have used technology to communicate with each other in a kind of geek version of CB radio. Any two computers connected on the same network can use VoIP technology, but there was no widespread adoption of technology. The first important step to VoIP that many useful services to today was the introduction of software called “Internet Phone” an American company called VocalTec. The first publicly available software f Internet Phone from VocalTec gap has been the catalyst for the explosion in the use of VOIP. VocalTec software was able to run on a PC at home and used much of the hardware as well as VoIP services used today in terms of sound cards, speakers and headphones. The Internet Phone software differed from most modern services in VOIP that used the protocol H. 323 instead of the SIP is now more pervasive. Although Internet Phone is an immediate commercial success, it suffered from a variety of problems. Lack of access to high-speed Internet means that quality may be poor and the flow of the votes slowly. Early VoIP calls, where as the use of walkie-talkies to communicate in terms of signal quality. Another problem was that the two computers where talking to each other should have the same sound cards with the same drivers to operate. This obviously limited the use of software and process efficiency. Much of the transfer was done via modems and then using traditional telephone lines and provide a service that was of lower quality than a normal phone call. Once VocalTec had laid the foundations of the increasing use of VoIP has been quite rapid accounting for 1% of all telephone calls from the United States by 1998. Other companies have begun to develop software for the VoIP market and also the equipment in terms of conventional phones and network switches. The growth of broadband has also contributed to the growth of VoIP in increasing call quality and reduce latency issues that VOIP done early. In 2000, the VoIP calls to the United States, where about 3% of the total. The popularity of VoIP has increased since the turn of the millennium with Free VOIP provider Skype has now recorded a staggering 400 million accounts of users at the end of 2008. With the increasing availability of VoIP services for mobile phones, it seems that the adoption of VoIP will continue to grow rapidly. Tony Heywood © Â VoIP is the word on everyone??
