The caller ID said CTI. The man asked for my husband and pronounced our last name wrong. He basically was rude and a smart alec. I tried calling them back to tell them not to call as we are on the do not call list, but it was busy all the time - finally got it to ring and they didn't pick up. I *think* he was trying to sell something and most likely something about investing as we've gotten a few of those, but I'm not sure.
