Voice over Internet Protocol is a means for translating analog sound data into digital bits and transmitting them across the Internet to another phone, a voicemail box, or a computer. VoIP is a fast growing technology worldwide, and as high speed Internet access becomes more and more widely available, VoIP is rapidly replacing traditional copper wire-based telephone networks everywhere. The reasons why are simple. VoIP service providers offer an array of advantages that regular phone companies just can’t beat. Features such as caller ID, voicemail, and multiple lines that often require costly extra equipment and even messy installation work by traditional phone companies all come standard with most VoIP service packages. In addition, when switching to VoIP service, users don’t even need to purchase new telephones, as many providers include free adapters, making the transition quick, simple, and easy. Best of all? Nearly all of the VoIP providers listed on this site offer unlimited calling plans, including long distance within the United States and Canada, at a fraction of the cost of traditional copper-based phone company service. Depending on usage, the phone bill for some homes and businesses can be lowered by hundreds, or even thousands of dollars per year after switching to VoIP service.
