Phone rang, I was expecting something important, but this wasn't it. Silence on the line even after I said something. I just hung up. Caller ID gave me this number as the caller.
I'm already on the "Do Not Call" list. At risk of sounding pessimistic (who, me?) I suspect it's from an overseas source who would be beyond the reach of the law.

Heavy foreign accent - probably female, possibly effeminate male. Call concerned a "meeting" later this month. However, no meeting scheduled for that day with anyone other than close associates.
