There is one specific person who is unable to make calls to me. I can make calls to them just fine but when they try to call me and I answer, there is no sound, not even static, and the call lasts for 10 seconds at the most before the call drops. Same thing on his end. He calls, it quits ringing when I answer but he hears no noise and then the call drops. We've both reset our phone settings (he has an iPhone 7 and I have a 5s). Other iphones are able to call me, just not him. We can text each other with no problems and like I said, i can call him with no issues, just can't call me.
