Same experience here at my office. The afternoon of 10/8/2012 there was a long pause and then a male asked to speak with "Mr. Jobs." I said "Ha, ha." He said, "Oh, do I have the wrong number?" I said, "Apparently so" and he hung up. About 12:10 p.m. on 10/9/2012, another call from the same number, again a long pause and a male voice asked to speak with "Bert." I said "You have the wrong number" and he hung up. Just a few minutes later, another call from the same number and a female asked "Is this Bart." I hung up.
