calls house everyday.  Sometime calls are less than 2 minutes apart.   Answered the third time, and caller identified himself as Josh, did not understand what he was selling, he wanted to know if I could hear him okay.  I replied stop calling this number, and blocked called.  I understand this is a scam, once they asked if you hear them okay, and you say yes, they record your yes response, and use it to authorize other scam calls.
