Voice over Internet Protocol is the newest way in which people are making phone calls today. Though the technology for VoIP has only been available for a relatively short time, it is already gaining worldwide popularity. VoIP is the use of a broadband internet connection for the purpose of making telephone calls. This has many benefits, most notably not having to put up with the outrageous taxes and fees that come with getting telephone service through a company.
There are three main methods in which to set up your VoIP, all of which even a layman can do. First, and most popular, is the simple computer-to-computer VoIP. Users merely download or purchase a “soft” phone (a computer program that acts as a phone) from the Internet that can be used to call any other computer with a similar program. In addition to the soft phone, a person needs speakers, a sound card and a microphone to complete a call.
The second option for VoIP is to purchase an analog telephone adapter. The adapter, once hooked up to both your Internet connection and your phone, can convert normal phone signals into signals that can be sent over the Internet. This has proven to be the simplest and cheapest method of setting up a VoIP. Popular companies such as Vonage are starting to bundle analog telephone adapters with low priced service agreements. The third method of setting up a VoIP is the use of an IP phone. Instead of regular connector cables, IP phones have Ethernet cards that are designed to be hooked into broadband Internet connections.
There are many issues that surround a VoIP including privacy, security and reverse phone lookups [http://www.instantphonelookups.com]. Though VoIP is a big money saver, it is always wise to research all of the facts before abandoning your traditional phone service.

An Overview of How VoIP Works

Voice over Internet Protocol or the VoIP, is basically the process of sending voice through internet protocol, making it convenient for a consumer to make phone calls at cheaper price. VoIP is used not only when using the internet protocol to send or receive calls, but it is also useful when you want to avail the service of traditional phone lines that guarantee better quality & allow bigger space for calls.
When the quality of audio and frequency in VoIP is high, it is very hard for customers to notice the difference between it and a normal telephone. Even the person who is receiving the calls from a VoIP will not be able to guess that the calls are made from a VoIP Network. Transferring PSTN (Public Switched Telephone Network) to VoIP/SIP Session Initiation Protocol) allows VoIP users to send and receive phone calls as done in ordinary phone lines.
Now, enough about VoIP from the scientific point of view. Let us now proceed to the benefits of using VoIP compared to using conventional phone lines. Basically, consumers care mostly about the rates so they would like to know how much can be saved when you purchase a VoIP service. This is one of the advantages of VoIP. It became popular because of its cheap call rates as compared to any conventional phones. It gives you the ability to make unlimited phone calls, long distance calls and low international calls charges with low monthly subscription rate. This is value added service for any consumer.
VoIP can be used in different ways. One possible way is through ATA or Analog Telephone Adapter. ATA is connected between a telephone jack that is already existent and an IP network in order to provide VoIP service. This type of service is generally offered by broadband internet providers such as cable companies and telephone companies.
Simply check the company that provides you with internet cable service or the company that provides your home phone service to see if they offer this service. If you want an easier way, just check the internet out for low rates companies. There are a lot of new companies that are just providing this service and they are concerned about giving the best service with lower rates.
Finally, a VoIP is a better & more economical way of making long distance as well as short distance calls by simply using an internet connection. You can use it for local, nationwide and international calls. You can even make calls to residential phones or cell phones.

How Does VoIP Service Work?
February 10th, 2010
VOIP technology is a one way of sending a voice signal also known as an analog signal in a medium which is digital, i.e, the internet. In practice, the process works like this when you have a standard analog telephone attached to your high speed internet connection with VOIP service. There will be an analog telephone adapter or ATA between the phone and the computer.
In order to place what would normally be a long distance call to a person who doesn’t have VOIP service you key in the number you want. The analog telephone adapter converts the touch tones into a digital format. The digital phone number is sent by the analog telephone adapter to the VOIP routing system at the service provider’s location. The VOIP service provider is located on the internet as well.
The VOIP service provider’s routing system identifies the recipient’s location and sends the call to the Public Switched Telephone Network (PTSN) at that location. The phone rings at the other end and the conversation can begin. Each time you speak, the analog to digital converter in the analog telephone adapter changes the voice tones into packets of digital information that can be transmitted across the internet. When the VOIP service meshes with the Public Switched Telephone Network at the recipient’s end, the digital packets which are the voice tones from you get turned back into an analog signal so that you recipient of your call can understand what you are saying.
The reverse process, i.e. the transmission of what the other person says to you is a mirror image of the first process. Their voice is transformed from analog to digital when it gets to the PSTN/internet connection. The digital packets are sent to the analog telephone adapter at your location where they are converted back into an audible or analog signal to be able to perceive the voice as that of your caller.
The technology to do the conversion from analog to digital and back again has been around as long as digital electronics. For example, your PC sound card converts digital CD information to analog signal needed by the speakers on your computer. The difficult part of the VOIP technology is the necessity to smoothly transmit the digital data over the internet and reassemble it in a continuous stream. This is know as the protocol.
When listening to voice transmission, there can be no gaps in the stream of digital packets or the voices will not be understandable. This part of the technology has only recently been available, but is actually equal or better in quality than you get with standard telephone networks.
The equipment available today that uses VOIP technology can be an analog telephone adapter for your head set through the computer. There are a few VOIP phones that act like a regular analog telephone but have the ATA incorporated into the phone. It’s actually a small dedicated personal computer in your telephone. These VOIP phones can be plugged into the computer with high speed internet connection or into the router.
