Broadband Phone & Broadband Internet?

I want broadband phone service and broadband internet service all from the same company that way i receive just 1 bill. I don't want to get a broadband phone from a different company and to keep staying with my ATT net service because i don't want to receive two different bills every month.
Is there any companies out there that offer broadband Phone ( VoiP ) and Broadband Internet in a package?
