Looks like you are the first to report. You might check back later today or tomorrow and see if there are other reports. If that is not your local area code or exchange, you are right to be suspicious, esp if no name shows up in your caller ID. Resist the urge to call back, that sometimes just gets you more calls.
Knowing who called is not much of a prize. If you are on the DNC, then this is apt to be a spoofed number, and you are being called by law-breakers. In my house, I know enough to block that number with prejudice. Crooks spoof and hide their ID.
