Simply put VoIP is a protocol that allows for a computer to make a voice communication over the internet. A computer can call a computer, or it could even covert the signal and call an ordinary phone. With VoIP a user can call using a computer, a phone made special for VoIP or a normal phone equipped with a VoIP adapter. VoIP can also be accessed wirelessly in certain areas where such a connection is available such as internet cafes and other such hotspots. Simply put, VoIP allows people to talk over the internet just as one would over the phone.



In order to take advantage of VoIP the user will need a broadband high speed internet connection. Cable modems as well as services like DSL or even a local area network will fit this requirement. The other thing needed is either a computer, a specialized phone or an adapter for a traditional phone. Either the computer or the VoIP phone would work better as some VoIP services will not recognize the adapter and will not function as a result. If the computer is the preferred method then specific software will need to be installed and a microphone will need to be connected. Other than the fact that the VoIP phone will attach directly to the broadband connection, it works like a normal phone.

Calling other VoIP users will normally be free of charge; however connecting to traditional phone lines will likely cost the user money based similar factors as a normal phone. Details of payment will of course depend on the VoIP provider. Some will allow the user to call anywhere for a flat rate while others will operate more like a current phone service. Who a user can call varies depending on the provider as well. Some will allow users to call any number whether it is VoIP or not. Others will be limited to only those who are using VoIP. In order to call a traditional phone, there is no need for any specialized equipment; the user simply dials the number as he normally would, making it the same as a normal call.

One of the main advantages to VoIP is that the user no longer needs a separate phone line and a broadband connection. Both the phone and internet now works off of the same line and so the user saves money and effort with the upkeep of two different lines. In today's world where cell phones have nearly make land lines obsolete, this is a huge advantage. Beyond this VoIP has available features that a traditional phone will not. These are of course specific to the provider of the service and what they are willing to offer.

While VoIP is not without its drawbacks, it is possibly the future of voice communication. As computers are becoming more and more accessible, the need for a separate device to handle voice conversations is becoming less and less. Given a decade or two the kinks inherent in VoIP will likely be worked out and it could replace land lines altogether.
