Just HANG-UP! It is probabaly a scam. Why? That number is a pay phone at Bayside State Prison in Port Norris, New Jersey. I received a phone call from that number. The telephone company's recorded message was asking if I'd like to accept reverse charge for the phone call. Thankfully the inmate must have been new at it because he was saying in the background - AT THE SAME TIME - "I'm calling from Bayside State Prison."
Luckly I could hear both the phone company's message AND the inmates and just hung-up.
