A:AnswerThis modem ( model C7000) does NOT have the telephone ports for connecting a phone line. You would need one that specifically states something like “plus voice” in the product description. When you look at the back of the product diagram, you will see ports labeled for phone connections on those that support telephones.
A:AnswerThe store techs said they only sell these routers that work with your local cable company. So that is smart on Best Buy's part and as far as it supporting all of your equipment yes it will and more. I have this router and its perfect so run and get it now before they run out.
A:AnswerYes you should be able to. I was renting one from Comcast and it saved me about $15 a month. It was easy to install you probably just have to call AT&T and give them the router information before purchasing it like the brand name and ask them is it compatible with their service. If so then buy the router and call them again and give them the model and serial number so they can pair it with the account. And you should be good to go from there.
