Please tell us what kind of NAT settings cause problems. What should we look for in our network or router settings to change?
I made a test call, and it connected, and I could see the GUI oscilloscope reflecting my speech, but I don’t know what the test call is supposed to test. Am I supposed to hear anything, including a “sidetone” when I speak? Because like any other call, I hear nothing. All it does is ring and connect, and the timer runs, but nothing else.
