Server error making call

[joaopneves]

Hello,
I have a Redmi note 8T. The cell phone always worked normally. However, at this moment when I try to make calls I can't, an error message appears ( server error, try later)
I don't know what to do. Can anyone help me?

When did this first occur? What firmware is the phone running, did you update, is your SIM working in another phone, more information is needed in order to help you...

First occurred yesterday. I have been using MIUI Global 12.0.3 | stable and my SIM work in another phone. I even receive calls but I can't make calls.
