Voice over Internet Protocol (VoIP) is one of the fastest growing and most misunderstood technologies in the world at the moment. Confusion, outdated beliefs and urban mythology reign over such simple issues as how it works, the quality of the calls, and, of course, how much it costs. This paper examines seven existing myths about VoIP. These myths are that: (1) VoIP is free; (2) the only difference between VoIP and regular telephony is the price; (3) the quality of service isn't an issue nowadays because there's plenty of bandwidth in the network; (4) VoIP can't replace regular telephony because it still cannot guarantee quality of service; (5) VoIP is just another data application; (6) VoIP isn't secure; and (7) a phone is a phone is a phone.
