The VOIP providers Top 20 review brings you the pick of the best and most popular VOIP service providers online today.
VOIP, or voice over internet protocol has come a long way in a relatively short period of time. The early pioneering days where VOIP involved complicated, low-quality phone calls using a computer have now matured to a stage where you can simply pick up a regular phone and use it like normal. The big benefit now is of course is the cost saving, with VOIP calls now typically costing just a mere fraction of the price of a regular phone call.
The range of VOIP services available starts with the immensely popular free services which are largely computer-to-computer services which use software phones. Although they don't come with a phone number, free calls can be made to other users of the same service by calling their username, (not their phone number).
Generally calling a regular phone number will involve a cost as the call will be handled by a carrier at some point, and this has to be paid for, and that is where the full service VOIP provider comes in. They enable you to use a regular phone just like normal. The phone can also have a number, and can call regular phone numbers (unlike most free services). The real benefit comes from the fact that it is very much cheaper using VOIP than a regular phone service.
Skype  is the leading free VOIP service provider in the world, and has been since it's inception in 2003. The service is available in 28 languages, and is used in just about every country in the world.
Skype is a piece of software that customers can download to call other people on Skype over the internet for free and make and cheap calls to phones and mobiles worldwide.
