recieved the same call today I also live in nj they did not leave a message I did call back the number by adding a digit to the end and 0 thru 9 came up busy, I also found out the exchange is located in wyckoff NJ
This sh*t *is* illegal. Unsolocited phone calls to a cell phone are absolutely 100% illegal in the US and carry a stiff fine of about $1000 per call to the violator.
As for the exchange being in wyckoff, NJ, 201 is actually most of north jersey. I've lived here for years.
Anyway, it's an ad robot. Pressed 1 to get more info and got silence on the other end.
