Skype, despite no advertising, is number one in the North American VOIP business. This according to Sandvine, a Waterloo, Ontario-based company that tracks the VoIP business. According to Sandvine, Skype accounted for 46.2% of minutes and 40% of bandwidth amongst all VoIP providers. Further more, Skype users also account for 35.8% of individual VOIP callers on North American networks. I guess its pretty hard to compete with “free” services.
