This number has called me twice in last 2 hours.  Leaves no voicemail.  I called it back using my blocked work phone.  Got the following:  1 ring, voicemail picks up, male voice states "You've reached Campaign phone bank.  We'll try calling you again later."

I was charged $.91 for an international call. I never called this number back (in fact, I never call numbers I don't know; instead I google the number and check it out--like this site). We received several calls from this number during the flurry of champaign calls prior to the November elections. I've registered this call with AT&T and they are checking it out. Should be receiving a reverse charge. You should check your December statement to see if you received an international phone charge from this phone number... especially if you know you did not call the number.
