Phone lines are obsolete
I had looked a little bit into the various Voice-over-IP services, but recently my coworker Ed said that he signed up for Vonage. It’s a phone connection with unlimited access for $25/mo., or 500 minutes a month for $15/mo. That’s much cheaper than a normal phone line, and calling anywhere in the country works. I’d been thinking of looking into it more when our house got further along, but I may sign up for it sooner than that (since I can just take it with me). I might not have a regular phone line put in when we build our house (or at least, I probably won’t activate it).
