Feedback for v1.12.3

My Teracube 2e emerald just updated from 1.10 to 1.12 and now phone calls do not work - it tries and then just indicates “Call ended.”

I tried clearing phone cache, resetting wifi and mobile, re-entering APN, and restarting. I tried another dialer. Nothing worked.

I see the same issue as this post: Phone Not Working
IMS registration - Not Registered
Voice Over LTE: Unavailable

Any help would be wonderful.
