에이티앤티(AT&T) - Rethink Possible

In 2004, the U.S. government eliminated equal access regulations that allowed long-distance phone companies to access the networks owned by the regional Bell carriers at fixed rates. This ultimately caused AT&T to move away from the residential telephone business — declaring in the process that it would no longer market residential telephone service. Instead, its residential focus shifted to offering a voice service over a broadband Internet connection called AT&T CallVantage.
