I just recieved two calls from this number (732) 000-0000. It obiously comes up Unknown Caller. The first time the person hung up, the second time, I heard someone talking in the background to another person. The guy asked the other guy if he had done mushrooms. Then talked about something else (too much background noise to hear) and asked if it's legal. Then the guy said to the other guy "I would have just hang up by now". Don't know if it's some kids fooling around with the phone system but I don't think they knew I could hear them. Mind you, I repeated said "Hello" and asked "Who is this", but got no response. I also heard a lot of keyboard typing in the background.
