I live in a small one-square mile town that has 2 unused phone booths - one inside a school and the other in a restaurant. Taking a page form an art project in Montclair some years ago I would like to create a "History Phone" that would allow people to dial a year, and then someone can hear something about that year in the town's history. I would also love the opportunity for people to leave a message that can be heard at either the same phone or the other phone in town. Can a Raspberry pi handle this?
