There’s no question right now whether VoIP is eventually going to become the default mode of telephony communication throughout the world, for both domestic and international communications. Instead, the real question is how VoIP will pursue its path to world dominance. Most likely we’re going to see a mix of different implementation methods. The major mobile carriers will likely switch all of their services, including telephone calls, under a single data plan, a shift that will effectively create mass adoption of VoIP regardless of whether mobile users ever become aware of the transition. But despite the power they have to make VoIP the standard for mobile communications overnight it’s increasingly clear the major mobile carriers aren’t the only players in the access or IP transport business with their eyes on new revenue streams, a point driven home by Skype’s recent initiative to provide free wireless across Britain.
