Recently, Hank Hultquist of AT&T posted some interesting food for thought on the evolution of voice services. His general premise is that the traditional public switched telephone network (PSTN) is as outdated and old-fashioned in the telecom world as the Edsel is in the automotive realm. Instead, we are moving to a world where voice service will be merely another application riding on a “broadband autobahn” of Internet protocol (IP) networks, and these IP networks will seamlessly interconnect without the need for pesky rules or government intervention.
