This call came to my cell. The man on the other end asked for my underage son, specifically. I thought it was possibly about a bill, so asked what it was about, explaining that my son is a minor. He refused to tell me anything saying it was a "private business matter" and tried to get me to write down an extension. I repeated again that my son is a minor and he needed to talk to me. Again refused. I hung up. Obvious scam.
