Over in India, the telecom minister urged carriers to stop charging for voice calls and derive all their revenues only from data plans. Is this kind of model sustainable, where voice becomes an outmoded and free technology and carriers turn entirely into dumb pipes who have no control over what passes over them? This is a step forward and hopefully will make Internet service more like a utility."
