Issues with receiving call

[madhacker3kxl]

Recently, phone will not receive phone call, it gets sent directly to the voicemail. It starts to work after setting the phone in airplane mode and off. After a while it will not receive any calls again. There are issues sometimes taking a long time to initiate a call.
I am running:

I have worked with asus support teams before about getting debug software running and sending data of previous phones. I am familiar with the process.

You are literally describing what happens if you don't have VoLTE support.
So I'll ask, do you have VoLTE enabled?

[madhacker3kxl]

Yes, I have VoLTE enabled. I unhid the VoLTE from the status icon. It use to show up before and worked just fine. I am with TMobile USA so it is supported and it did work.
Only after the last update I started to have an issue. I will disable VoLTE and see what happens.

Check if it still shows up as well, just to make sure it didnt break on a recent update.

So VoLTE icon did show up. But if I initiate a call it goes away. So it seems like it's not working. Turned wifi off to see the mobile data speed. Normally it's 5G, initiate a call it drops to 3G, thus loosing VoLTE status. That for sure I know it didn't happen before the last update.
