How to diagnose bad wifi calling quality?
My house is a farraday cage, and I *have* to use wifi calling. It's not great. Sometimes I get robot-voice, underwater-voice, and really bad audio dropouts -- like I'm hearing every third word. We have have gigabit fibre, and the call quality issues occur with both a Pixel 7 and an LG G7. The only thing I can think of to do is check jitter and packet loss with a tool like PingPlotter (although I concede that this won't be conclusive; Wifi Calling probably uses UDP). Can you link me to technical information about how Wifi Calling works, and how to figure out which Telus servers are in use? Any other diagnostic suggestions would be appreciated.
