This phone number 4152311572 is a scam. I said hello, heard a beep, then was asked "hello, can you hear me?". DO NOT SAY YES. They are trying to record people to say yes so that they can sign them up for services and charge them. http://fortune.com/2017/03/28/yes-scam-phone-call/
This 4152311572 been calling me twice since 8:30am. Rude. No voicemail for me so I called back and yup, they are from some kind of company telling me I won something. Scam scam. I just silenced and let them "hello hello" 'til they hang up.
4152311572 is a scam, telemarketer of sort.
