VoIP stands for Voice over Internet Protocol. By using a VoIP phone and VoIP technology you can effectively use the internet to make phone calls. VoIP does this by placing the voice calls on network which encrypts the voice in data packets at one end and encrypts it in voice calls at the other end. In VoIP, encryption and decryption is from a analog signal (i.e. your voice call) into digital signal (data packets) and again into the analog signal.
You can make VOIP calls by a regular phone with VOIP adapter or even from your computer using a simple microphone. VoIP applications can generally be used with a simple microphone and computer speakers, but IP telephones or VoIP boxes can also be used, providing an experience identical to normal telephoning. Many VOIP manufacturers are designing phones which are specially meant to work with this technology, called SIP phone, and now extensively used by growing VoIP users.
In the past year, the quality and reliability of VoIP technology has improved to the point that vast numbers of users have abandoned their standard telephone contracts entirely, in favor of VoIP. Local as well as long distance calling is available for VoIP. Rates and plans can vary from one VoIP service provider to another VoIP service provider.
Advantages of using VOIP
Using VOIP you can effectively cut down your phone bills, since you just pay to your regular internet connection and small fees to your VOIP service provider. Setting up conference calls with VOIP is very easy.
You can even set up your own VoIP network and don’t need any special equipment like PBX etc. You can call to any local telephone, mobile, long distance number or any international number through VoIP phones. More importantly, the person you are calling by using VoIP technology does not need any special equipment; just a regular telephone.
Many additional features like call forwarding, call tracing, reminders, caller ID are readily available in VoIP Phones. You can even assign a local telephone number to your VOIP phone set, and just need a fast internet connection to use your VOIP service anywhere in the world.
VoIP Dilemma
VoIP applications and services require data transfer in real time. During a call an interactive data voice exchange takes place. Unfortunately, TCP/IP is not well suited for this purpose. Sometimes you have to wait for a few seconds, to hear the other side answering. But with recent developments streaming the flow of voice signals has improved. PC-to-PC and PC-to-phone calling quality is still not as sharp as regular PSTN calls. However, with SIP phones and a reliable high speed internet connection there is little or no difference….and sometimes the quality is even better.
SIP Phones
SIP Phones are the phones which are specifically designed to work as VOIP phones. SIP phone can be considered as a network endpoint routing voice via its IP address. This allows a DID (direct inward dialing) number to move with a user. With SIP phones you can use advanced features like voice mail to email etc. Using a SIP phone also closely resembles a regular analog phone in look, feel, function, and ease of use.
FCC and VoIP
The Federal Communications Commission (FCC) regulates VOIP Services in the USA. They are in charge to create and promote telecommnuication regulations….such as VOIP services….to benefit consumers. In November, 2004 FCC ruled that individual States do not have the jurisdiction to impose taxes on VoIP services, which made the cost of VOIP services even more attractive in relation to standard PSTN phone services.

How Does VoIP Really Work?
January 30th, 2010VoIP 101
December 23rd, 2009
VoIP is a relatively new type of telephone service that has been gaining more and more popularity in the past few years. VOIP is short for voice over Internet protocol, which basically means your phone calls are made through an internet connection, rather than through regular phone land lines. The rise of it’s popularity could mean that it will be the way of the future for most home phones. What is it that has all these people so excited about VOIP technology? Well, with VOIP you save quite a bit of money, when you compare it to standard land line telephone service. VOIP providers usually have unlimited calling, as well as free added features like caller ID and call forwarding, which would cost you extra with a standard phone service.
Those combined savings can add up to a savings of hundreds, or even thousands of dollars for many people. The biggest group this appeals to, and that stand to save the most, are larger companies or corporations that make a large number of calls on a daily basis. That doesn’t mean it won’t save money for those who only need it for their home phone, just that the more you use your phone, the more you’ll be saving.
Some might tell you that using the internet for voice chat can be choppy or get an echo, thought this can be true, VOIP uses RTP (real time protocol), which greatly limits and often completely eliminates such problems.
VOIP is not just useful for making and receiving phone calls either, it can also be used for other things, such as sending and receiving other types of data. File transfer is possible through a VOIP service, so you can share pictures with friends, or even send important documents instantly. Video chat and instant messaging can also be done through VOIP, when teamed with the right program, such as Google Talk or Skype.
With all these great features and the savings included, many people are making the switch. So much so, that even some standard telephone companies are starting to offer VOIP service to their customers, a sure sign that it’s here to stay.

What is VoIP Technology?
November 28th, 2009
You may have heard the term Voip used a lot in the media, but are not sure what everyone is so excited about. Here you will find the answers to your most sought after Voip technology questions.
What is Voip technology?
Technically, VOIP is Voice Over Internet Protocol, or voices traveling over internet lines and wires like other information would. So, what does this mean to you? A lot. Even if you don’t have a clue what Voip technology is, you may still be utilizing it everyday if you have a digital phone line or if you use a microphone hooked into your computer to speck to others while you are connected to the internet.
What is Voip technology going to do for me?
Digital phone and services like it keep costs down for the company, which is passed on to the
consumer. It is usually much cheaper then a traditional land phone line, especially if you want extras such as caller ID and call forwarding.
What is Voip technology going to lack?
As great as Voip technology may be, there are some drawbacks that one using it for your phone service should realize. First, most digital phone companies do not provide access to emergency assistance numbers, such as 911 for those in the US. This may leave your household vulnerable if you use digital phone. Some consumers overcome this by keeping a basic plan with there traditional phone company provider or have a cell phone available in case of an emergency.
Another drawback to Voip technology in the form of digital phone is that if your power goes out, so does your phone. When you have a service through a traditional phone company, you can still access your line even during power outages as long as you do not need a second power source to run it (ex: cordless phones need a second power source to run, so when the power goes out so does your phone). This is not so with digital phone. However, once again having a basic plan with your traditional phone company or having a cell phone on hand may remedy this problem.
What is Voip technology overall?
Voip technology can be an asset to anyone. It keeps the cost of having a land phone line cheap while still allowing us to communicate verbally without having to rely solely on cell phones. The next time you are taking a look at your high-price phone bill from your phone company, take another look at digital phone and Voip technology in general. You may rack up savings that you never even knew existed.
