We still have our number, which is the only number this house ever had. We also have the old black telephone that my wife's grandparents used. We don't have VOIP as far as I know. The tech had a hard time getting our current phone system to work with the new stuff. We have a big box screwed to the wall and another box sitting next to the TV and current phone.

We had a built-in phone shelf outside the kitchen in our previous house. When I was preparing the house for sale, I removed the phone shelf, as people don't use them any more.
