Fairphone 3 - Incoming calls appear as 'Unknown'

For what it’s worth, I don’t have this issue with a Telekom SIM card, VoLTE on, Wi-Fi Calling off (don’t need it), on 1.6-s-20221201239247-dev-FP3 … [HOWTO] Give complete /e/OS version info easily for support, answers, comparison etc.

Edit: I just enabled Wi-Fi Calling and called the phone from a different phone … still no issue (and it was indeed announced as a Wi-Fi call).

So, data points:

User Issue? /e/OS version Network VoLTE WiFi Calling
@awc ? ???-q-2022???-stable-FP3 Virgin ? ?
@awc no issue ???-?-???-???-bullhead Virgin ? ?
@crc issue 1.6-r-20221129238947-stable-FP3 ? ? ?
@AnotherElk no issue 1.6-s-20221201239247-dev-FP3 Telekom on on

We might have to work on the question marks.
