I received this robo call which is interesting because I had just received the same call from a 201-243-3399 number with the same robo call spiel. What a waste of my time answering.
I received a call from this number on my business line. It is an autotron informing me that my vehicle warranty was about to expire and that this was my second and last notice before they closed the file. I have no vehicles with factory or dealer warranties so I knew it wasn't legitimate. It did give me the option to press a number to remove myself from the callback list, but since I wasn't sure what exactly that would open me up to, I just hung up.
I got a missed call from this number, no message was left. I called it back and it said, HELLO IF YOU WOULD LIKE TO BE PLACED ON THE DO NOT CALL LIST PRESS 1. then it just kept repeating. I pressed 1 and it said it would take 48 hours to take affect. Other websites say that it is a spam call about vehicle warranty expiring (which I know I do not have)
