VoIP

VoIP (voice over Internet protocol) is a new revolutionary technology that can change telephony as we know it; it basically works by sending the user�s voice in digital packages through circuits that are only usable for telephony, like a conventional phone company or PSTN, the protocols used by VoIP to send its signals are commonly referred as voice over IP or IP protocols.

VoIP allows any regular Internet link to be converted and used as a media to make free phone calls to any part of the world, this signal is sent through the Internet into one person�s computer into another�s, where the inverse process occurs so the voice of the first one can be heard again. In this way we reach to the result in which the end is a phone call completely free of charge.

Implications for the phone industry are huge, because this technology threatens with disappearing the traditional phone companies, in which companies charged high prices per minute in long distance calls. In the United States there are already companies such as Vonage, which offers packages of unlimited phone use for a low monthly installment. Finally, traditional telephony companies such as aT&T and Verizon are preparing themselves to avoid these new technologies taking them by surprise.

Here we will see what types of VoIP exist, how their technologies differ from one another and how we can take advantage from this technology to enjoy free phone calls. Types of VoIP � aTa � this is the easiest way of using the VoIP, which is simply an adapter with two connectors, one plugged into a regular phone and the other one plugged into the Internet access line. Its abbreviation stands for �analogue Telephone adapter�.

If you are interested in trying to make phone calls through the VoIP system, you need to check the software available in the Internet. The most common ones and simpler to user are: Skype (http://www.skype.com) and Google Talk (http://www.google.com/talk/), although recently MSN Messenger and Yahoo have also included this basic functionality.

another advantage that is has over regular telephony is its quality level, because through this type of signal, the property of silence suppression is offered, which grants more efficiency when having a voice transmission, because it uses better the broadband when transmitting less information.
It also makes a priority transmission packages that have a lower time of delay.

Summarizing, this new technology has a great potential ahead and it could be the solution to the problem that most people have with the monthly installments that come for using the phone, this technology will be the next revolution in the digital communications era.
