I didn't recognize the number, and the caller ID showed "Almont, MI." I don't know anyone there. Also, I'm on the Do Not Call list. I didn't answer the phone. No message left.

If you don't recognize the phone number... let it go to the voice mail or answering machine. Most times it's a robo-caller to see if the number is active and what time(s) you'll pick-up, so that in the future a company can call you back with a "live" call.
