Does anyone know of a way to have a phone number for people to call and hear a recorded message?

Sort of like and internet answering machine service I guess but without the "message leaving" part .

I don't know about the actual setting up of the phone service, but you can use DTMF tones as a way for phone users to interact with software. I'm sure I have seen a DTMF Arduino shield which can answer the phone and help you decode the tones.
