Android 12 Broke ROG Phone 3

[Aerevyr]

Please tell us some basic information before asking for help:
Model Name: ASUS ROG Phone 3 (Strix version I believe)
Firmware Version: Version WW-31.0210.0210.230
Rooted or not: Not Rooted
Frequency of Occurrence: Persistent (no variation)
APP Name & APP Version (If your issue relates to the app): Phone App
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
After Updating to latest Firmware Version the Phone app immediately "Call Ended" upon dialing a number, with the exception of emergency services (911) takes about 30 seconds but begins to ring.
Incoming Calls go straight to voicemail.
VoLTE option is not found in settings except in the "STATUS BAR ICON MANAGER" section where I can choose to have it display in the status bar (it doesn't display)
I have :
- Restarted the Phone
- Shutdown and Turned back on the Phone
- Enabled, waited up to 30 minutes, and Disabled Airplane mode multiple times (dozen+)
- Factory Reset the phone
- Installed Alternate launchers
- Gone through support with my Carrier (no issues on their end the SIM and everything works perfectly fine in non-ASUS-Android 12 phones)

I had rolled back to Android 11 on the 18th. I made sure auto update overnight was off. Tonight my phone said reboot to finish update, it had updated to Android 12 again. I ran a backup and rebooted. It actually works this time around so they must have fixed it. Still ugly AF UI though.

Nope, no root. I did manually configure APN to match what's listed in T-Mobile's help article, because (if I remember correctly) the default configuration didn't match up.

Oh, there was one other thing I did: I used adb setprop to forcibly enable VoLTE support... and it seems to have worked, and stuck enabled even after reboots and updates.

However, I don't think I did anything specifically about LTE and 5G support.

Oh that explains it. So the voLTE configuration worked just fine the slider was just disabled. Here most people have the opposite problem, they can enable voLTE and its apparently provisioned, but it won't work.
