I get a large number of calls to my cell phone from numbers I don’t recognize. Without fail, answering those numbers means I get the privilege of hearing unsolicited sales. My Samsung phone recently pushed an update/app called Call Screener. Using that app, I see these calls all come from VOIP numbers. If you have legitimate business with me and are using VOIP, you better leave a message or call from a different number. I am routinely putting all VOIP numbers on block now. Thank you, Samsung!
