    I have a OnePlus 9 Pro 5G. Latest software, OxygenOS If I make or receive a call on mobile data, no issues. If I make one or receive one over Wifi calling, I can't always hear the other person, and they can't always hear me. Sometimes it works but most of the time it doesn't. There's no rhyme or reason. I'm using T-Mobile for my carrier, but I bought the phone unlocked from OnePlus. I've noticed some other threads with this device and other models mention the same issue. I have reset my network settings, but that did not solve it. I used WiFi calling with T-Mobile on both Samsung and Apple phones before, and my wife currently uses it with her iPhone and has no issues. So I doubt it's a T-Mobile overall issue. Any info on this problem and a possible fix would be appreciated. Thanks
