I called back with my number blocked. It's 'Dan' with 'Security Specialists'. Same people call our other cells constantly trying to sell a security system. No thanks!
It only rang a few times. Caller ID showed only the phone number. Thought it might be someone we knew from Cincinnati, OH, the source of the call. I called back on different phone: "Dan from Security Specialists". Ha! Told him I had the wrong number and hung up.
