We are trying to make a VoLTE call in Poland using BG600L-M3 using Orange SIM card with enabled VoLTE.
After updating firmware to BG600LM3LAR04A01_01.200.01.200 we are able to start connection, but it fails after all with “NO CARRIER” message.
Connection log:

Could I miss proper mbn file as it was in post: VoLTE in BG77 and MBN files
I’ve collected some info about my setup, in case it could help:
