General Information: All telephones have a jack where you plug in the phone cord. The phone jack is connected to the wall jack, which connects to the telephone company's wiring. So even if you have two phone lines up and running, if you plug the two-line cord into a single-line phone jack, you'll still only receive calls from the first line. It's possible to use two phone lines without using a two line phone, but you have to either rewire your wall jacks or purchase a two-line (or more) splitter. These devices plug into a standard two-line jack and split the line, directing the first line to one jack and the second line to the other jack. With a splitter, you'll just have two single-line phones coming off the same jack. One of the phones will receive calls from line one, and the other will receive calls from line two.
