An anonymous reader sends word that the U.S. Federal Communications Commission has given the go-ahead for telecommunications companies to start experimenting with an IP-based telephone protocol. From the article: "The experiments approved by the FCC would not test the new technology - it is already being used - and would not determine law and policy regulating it, FCC staff said. The trials would seek to establish, among other things, how consumers welcome the change and how new technology performs in emergency situations, including in remote locations. 'What we're doing here is a big deal. This is an important moment,' FCC Chairman Tom Wheeler said. 'We today invite service providers to propose voluntary experiments for all-IP networks.' The move in part grants the application by AT&T to conduct IP transition tests as companies that offer landline phone services seek to ultimately replace their old copper wires with newer technology like fiber or wireless."
