No one answers when I say hello.  wait a few minutes
then I hang up.  Irritating.

Same thing for me.  Answer and they hang up.  Probably the Obama minions or NSA.  Parasites!

Caller ID shows Boar Head Inn. I don't answer.

I got this and half a dozen other Virginia-based calls, though one had an invalid area code. All are different numbers, so must be a boiler room set-up. Probably disposable cell numbers.
