Just a spam caller that will only prompt a pre-recorded message when you make noise into the mic after picking up the phone. Not saying anything or making any noise will cause the robot to hang up after 5 seconds. I've purposely been making a noise and quickly muting myself afterwards, so the call goes through to the spammer after sitting through the pre-recorded message. He answers, and i sit there in silence while he says "hello?" I will continue to do this for as long as he calls me lmao.
