Unknown callers going straight to voicemail
iPhone 11 version 15.2.1
DND is OFF, Silence Unknown Callers is OFF, no headphones are connected, the volume is all the way up and I can hear it ring for any of my contacts. Did a test call from a number that is not blocked. I have done several hard resets. There is no reason these calls should be going to voicemail automatically. Why is the phone not ringing for any number not in my contacts?
