Called at 3:45pm, Nobody on the line, but a lot of other conversations going on in the background, i.e. a very busy phone bank, I think. I said hello 3 times and they hung up. Very annoying.
Call came from the St. Louis suburb of Oakville to Kansas at 17:32 hours CDT on 9-23-11. Call not answered and no message left. Later investigation developed that this number is in the phone bank of Madallion, the non-profit fund raiser outfit.
