All incoming calls are Unknown number (no caller number visible) when VoLTE is activated.
No issues with outgoing calls (that does make sense). When VoLTE is deactivated, everything works okay. Turning the feature on/off, also with enable/disable carrier check, does not solve anything.

Anyone know how to solve it?

1- Download Activity Manager
2- Open the app & go to Activity list tap
3- Search for ( Modem Config )
4- Tick on the one that have ( vodafone/volte/netherla ) in its path

I used to have this issue for more than 3 months and I have tried all the available solutions
and only this one worked for me

I got 12.0.9 on Poco X3 and I have exact same problem in Poland, Play network. Moreover on Poco there is no modem config I can modify.
I had stock EEA rom before and both VoLTE andd wifi calling worked fine. Now VoLTE caller id is not working and wifi calling is not working at all.

Thank you for your tread. Because of that I switched off VoLTE for SIM slot 2 and calls are displayed now :)
I have a Redme Note 8T dual sim with MIUI Global 12.0.2 stable (RCXEUXM).
The problem exist only when I switch VoLTE option ON for SIM slot 2. This option is ON for SIM slot 1 and I can make VoLTE calls via SIM slot 1.
Tried to switch VoLTE OFF for slot 1 and ON for slot 2 but the problem stil exist. So for me it's only slot 2 that have the bug.
Reported to xiaomi via the settings-service and feedback-sent feedback. Hope for a def fix.
But I can use the phone now ;-)
