No message just hangup.

Called my house 8 times in the past hour, I no one from Greenfield Indiana.

No idea who this is, but they just called at nearly 11pm. They left no message, and then called immediately right back and there was a silence, a beep and a machine saying "Goodbye".

I don't know anyone from Indy which is where the 317 area code is from so yeah... what or who is this? Caller ID just says "Greenfield IN".

They were trying to sell health insurance. A little pushy!

I started answering the phone "Bar & Grill" when the caller id shows an unfamiliar number.  Confuses the daylights out of the live caller...they hang up, I call back to see if they wanted a reservation!
