Re: WiFi Calling not working properly

I did some extensive troubleshooting tonight.  The short answer is that the problem was  AdGuard DNS!  I had private DNS enabled with a custom DNS set there.  I was able to get WiFi calling working properly by turning off private DNS...but...private DNS was not the issue.  I was able to reproduce the issue by setting my router to use the custom DNS servers.  Private DNS set me in the correct path to solve this issue because it was DNS related.  I am going to do some DNS logging to find out what requests are being sent out when I receive an incoming WiFi call.  The custom DNS server is blocking something that is required by only the samsung phone in order to receive incoming WiFi calls.
