How does VoIP work? Like many people, you may have already heard of VoIP. If you weren’t born in this decade, you may still wonder what it really is. What can VoIP do for you and how exactly is it useful?
Basic Concept
VoIP stands for voice over internet protocol. These days, it is considered an alternative to the typical method of communication involving telephones. Instead of using telephone sets that transmit analog signals, VoIP converts these signals to digital chunks. These are reconverted to audio data when it reaches the recipient. The entire transmission happens over the internet. Although VoIP technology is still far from being preferred and considered standard, some people think that VoIP will eventually replace telephones. It could very well be the next step in communications technology.
The Specifics
So how does VoIP work exactly? VoIP is best understood by understanding typical phone calls first. Regular phone calls make use of what is called circuit switching. When you make a call, your call is passed through a series of switches starting from your phone carrier. Once the other party answers the call, the circuit between the two of you is opened.
Instead of circuit switching VoIP uses packet switching. In this technology, your voice is converted to little packets of data. These packets of data come with their instructions of where they should be sent. They are then sent through a variety of possible routes. They take the nearest router and are passed on to succeeding routers until they reach the recipient. When the packets are received, they are reassembled into a form that can be understood.
Advantages of VoIP
VoIP can offer all the features and benefits of a phone service. Its advantage over traditional phones is that VoIP calls can be made from almost any part of the world. Wherever there is an internet connection, you can have VoIP. The technology can provide cheaper calls than standard telephone technology. This is mainly because VoIP does away with costly circuit switching.
Disadvantages of VoIP
VoIP can be fast, convenient and cheap. It has, however its own disadvantages. These disadvantages are basically due to: (1) the current reliance of present systems on telephone technology; and (2) the shortcomings that plague computer technology.
Telephone Connections – Such services for example as security and cable still rely on telephone connections. Unless the whole country or world agrees to switch to VoIP, these services are likely to stick to their old methods.
This is not the biggest concern though. Since VoIP relies on internet technology, it is also susceptible to the problems that confront the internet and computers. You can therefore expect such problems as viral attacks, crashes and stolen packets.
Now you know the basic answer to how does VoIP work. In reality, this piece of technology does hold a lot of potential. Like everything else, the old ways of communicating over long distances can change. VoIP is the first logical shift that can be taken. It may take a long time however, before VoIP can become a fully integrated and snag free system.

How Does VoIP Work? Understanding The Basics
February 28th, 2010What You Need To Know About VoIP Broadband Telephone Service
January 28th, 2010
If you haven’t heard much about VoIP before now, you certainly will in the future due to its rapid emergence as a major communications technology. VoIP stands for Voice Over Internet Protocol, and it basically is the ability to make telephone calls over the internet to either a receiving computer or telephone.
For years standard telephone lines have used a circuit switching network to transfer telephone calls, but VoIP technology uses something called packet switching instead where audio is converted into packets of data that are sent over the internet and reassembled on the other end by the person’s computer or telephone. If a high-speed internet connection is used, a conversation can take place that easily compares to a regular telephone call in sound quality.
All of this may sound like a very new technology, but in reality it’s not. Programs that make use of VoIP technology were springing up on the internet more than ten years ago, although they were much less capable than those that are available today. Also every year continues to bring higher standards of quality for VoIP applications, and it will no doubt be a viable technology for many years to come.
A good example of the use of VoIP technology is instant messaging programs. If you have used an instant messaging program that is voice enabled, where you can communicate by audio, video and chat, it is in large part due to VoIP. This is because VoIP is able to integrate audio, video, data, e-mail, and more simultaneously. Although most consumers will use VoIP for telephone calls initially, many businesses are already finding expanded uses for VoIP technology.
Several telephone companies are realizing the potential for VoIP services and so companies like Sprint, Verizon, AOL and others are now offering VoIP plans to consumers. One of the distinct advantages of buying a VoIP solution is that it costs significantly less than most standard telephone services. In fact, most service plans will allow you to make unlimited long-distance telephone calls on your VoIP plan for very inexpensive rates. And the subscription rates are usually free of many of the taxes and regulatory fees that often accompany your local telephone bill.
Another major advantage of many of the current VoIP subscription plans that are available is that they often include extra features such as call waiting, call forwarding, three-way calling, voice mail and much more. Quite often, these extra services cost more when included by your local telephone service, but VoIP plans usually include them at no extra charge. Another interesting side benefit is that many providers will allow you to select a new area code and phone number for your VoIP calls, so if you have family or friends in a distant town, they can call you for free on a number that is local to them.
Hopefully this information on VoIP technology will help you understand more about how it works and how it can be beneficial for you.

VoIP Technology is Breaking the Chains of the Traditional Phone Companies
November 11th, 2009
Before companies like Magic Jack and Vonage we were slaves to the traditional land based phone systems. Big phone companies like AT&T and SBC (just to mention a couple) had us at a disadvantage and they knew it. With traditional land lines, every feature had a fee, even keeping certain features off you phone cost money. After adding up all those fees, along with your local and long distance, your phone service could cost $40.00, $50.00, $70.00 a month or much more depending of what features you tacked on and how many long distance calls you make a month.
Well I’m probably not telling you anything you didn’t already know. So how about something you may not know about – VoIP and companies like Magic Jack, Vonage and Skype are paving the way for this money saving communications technology. VoIP like Magic Jack and Vonage is finding their way into homes, not only here in the US, but around the world.
VoIP (Voice over Internet Protocol) – allows and analog signal from your phone to be converted into a digital signal that can be then be sent over the internet (much like a email) instead of over a wire network like the ordinary land line. This allows the user to make long distance phone calls for free or at a much cheaper price depending on the service used. Vonage is a pioneer and one of the most popular of this new telephony technology.
There is now a small host of companies offering VoIP services that will continue to grow as (VoIP) is the future of communications. Magic Jack is such a company and is growing in popularity as more and more people are becoming aware of this new technology. Magic Jack is the only service that has its own network system which is one of the most compelling reasons the service is so inexpensive.
While other VoIP companies are offering good products for reasonable prices, none can beat the price or can offer the simplicity and the flexibility of Magic Jack. The Magic Jack device plugs directly into an available USB port (2.0 or higher) the software in the device makes contact with the Magic Jack home base and after only a few minutes it takes to set up your account and phone number, you are ready to go. You can then take your phone that had been plugged into the land line wall mount and plug it directly into the Magicjack, lift the receiver, hear a dial tone and start making calls.
Companies like Vonage must pay for the network they use, so it comes with a low monthly bill. Magic Jack has one low price you pay annually which is less then one month’s bill of a traditional land line. Magic Jack will let you opt in for a multi year agreement that saves you even more money. Skype is another popular VoIP company that is much better then the traditional landline but has limitations such as phone calls are only free if you are calling other Skype users and must purchase credits in order to call someone using phone services other than Skype. This would kind of be like buying minutes for cell phones.
Magic Jack is not a phone or software installed on your computer; it is a device with the software installed in it that plugs into your computer or any other computer with a broadband internet connection. This means you can take the Magic Jack with you on long trips or even out of the country and make free long distance phone calls back to the US or Canada for free. How’s that for flexibility?
