Internet Telephony Magazine gives high marks to AT&T and provides a very comprehensive summary about the company's VoIP efforts beyond CallVantage.
What I like about this article is that it brought together what AT&T is doing overall and paints an easy to grasp landscape of how AT&T as a company is moving in the VoIP direction. No other company in the space has laid out their roadmap so clearly. If anything, the other companies that can really compete with them, MCI, Sprint, Level3 and possibly BroadWing have so many different initiatives going on, with internal factions working at cross purposes, that a message like this never gets out.
Kudos to the author for writing such an easy to grasp story, and to Dave Dorman for pulling this approach together so soon in an industry usually tangled up by their Cat-5 cables.
