Caller ID came up "Unknown Caller". I think he was trying to leave a message, because a man's voice came on, sounding like a recorded message, saying "Hello, this is Greg", then the message scrambled and I could not make out the rest of it. I have no idea what this was supposed to be, but assume it was another telemarketer. I get so TIRED of this. We're on the DNC list, but it doesn't seem to be working any longer.
