I've been talking on the phone with Rob for almost a year and a half now and he sounds nothing like Andy! So I don't think that's possible... unless Andy had a voice transplant! HEY WAIT A MINUTE!!! Didn't Steven Maddox have one of those voice box thingies??? HELLO!!!
Yeah, I think it's him. Andy definitely would have to have done something with his voice and his face. Haven't you ever seen the movie Face/Off with John Travolta & Nicolas Cage? But the difference here is, Andy and Rob switched their faces permanently.
