Thanks so much for coming back to me. We have a two-lline base station... Panasonic Kx-TG9321 (which is rather old) and some cordless/wireless extensions in the house, each with a "line 1" and "line 2" button. The phone line out of the wall and into base station is a RJ-11 or RJ-14 (not sure which) with four color wires: red, black, green, and yellow. It goes into the "Line 1 & 2" jack on the base station. So, if I signed up for the Xfinity phone services (and dumped ATT land line) how would I connect that red-black-yellow-green RJ-14 cord to the Arris gateway, which has both "Tel 1" and "Tel 2" jacks on the back? Maybe using a splitter (see pix in previous post in this thread?) Here is another question. I would not be adverse to buying new phones for the house if that would be easier. Does Xfinity sell phones? I'd want one base and 5 extensions if possible (One technology I'm looking at is dumping the land-line (ATT) and using our two cell phones with a new Panasonic base and extension phones called Link2Cell. I don't know much about it.) Do you think there is anyone at Xfinity I can call who understands this stuff. I'm a software engineer so I know a bit of tech, but not much about POTS!
