This is an AT&T-brand corded telephone, model CL2940. This item is used and at the very least powers on. Given that our home doesn't have the phone line anymore I don't know if will work as a phone again. I know there are services where you can use an old phone with an internet line, I don't know if that will work with this one. Anyway, it powers on with batteries and I can include a phone cord, too. It's has light wear and is pretty clean overall.
