The main advantage using VoIP is the cost of using VoIP when in comparison with standard land-phone call costs. Using VoIP to communicate with other VoIP users or even standard land-phones can be much cheaper than a normal land-line to land-line call, this is especially apparent with long distance calls. VoIP is a relatively new product but you can already find reliable services that enable you to connect with other VoIP users and reach landlines all over the world for a reduced cost.
