The majority of calls today are “missed calls” in that I do not answer them. My iPhone allows me to automatically send anyone not in my contacts list directly to voicemail. I hear a lot fewer offers for car warranties this way. As soon as I open my phone, I see a count of missed calls and I can check if any were real. I would not want my phone to make noises to try to attract attention until then. Perhaps that feature is becoming less useful to people?
