OnePlus 8-5G Wifi Calling has no sound

My new OnePlus 8-5G phone (TMobile in US) cannot consistently send/receive wifi calls. Once answered, there is no sound on the OnePlus 8-5G phone while the other end can hear OK. I’ve tried updating the phone’s software (it is up to date) and I have updated the firmware on my router (which works with wifi calling with other phones: iPhone 11, iphone8, Droid Turbo 2, Motorlla Razr MAXX). I also tried disabling any battery saving features on the device and even did a factory rest of it (with no apps installed). I have also tried rebooting the phone once I have connected to the wifi router. Phone has same issues on any wifi router I have connected to. browsing is fine, only wifi calling is a problem.
