It's a robo call for the Georgia State Fraternal Order of Police pushing their fund raiser.  It calls your number then cuts off.  If you call back, it starts it's schpiel with a pause long enough to reply to the questions, generally "yes" or "no" and then continues through a series of options on how much you're going to sponsor them at.

If they were honest enough to have on the Caller ID that they were this organization, I wouldn't have too much of an issue with this.  But to call, disconnect, and use "Private Name" on the caller ID is more than a bit dishonest.

Best to just not answer.
