Unknown calls won't come through to iPhone 13 - Settings does not resolve the issue
My wife works for the Department of Defense. All of the calls from her work come in as "unknown" calls. I have already gone into my settings and have turned off "block unknown calls." My son has an iPhone 12 and I have an iPhone 13. Neither of us can get calls to come in to our phone when she is at work. To make matters worse, due to the high security nature of her job, she can't have a cell phone inside the building, so she literally has no way of reaching myself or my son. Does anyone have an answer to this besides the obvious settings step that I have already taken?
What makes things odd is that I have a work iPhone XR and my daughter has an iPhone 12 pro. The calls come in just fine to those phones. (Same carrier).
