@messayisto calls show up and you can respond or hang up, but there’s no audio, so you can’t hear anything and the one on the other side also can’t hear you. So not usable, but it partially works.

The code is available here now: https://git.deusch.me/ubports/device-google-tegu

For now, this is more of an experiment than a real port, but there are instructions for flashing in the repo if you‘re brave.

A disclaimer: there’s AI generated code involved and I can’t vouch for the quality of the patches. Most notably, I had some keyboard crashes that are likely related to the pulseaudio code not properly cleaning up its resources. I didn’t have time to look into that yet.
