@devrtz @agx @me And it‘s really great news, because I stumbled about the same issue and had to solve it by using a hardware phone to be able to keep using Linux on my device for daily work. Happy to try Calls out! Thanks! (Yes, I supported this by donating to Purism.)

@devrtz @agx @me Ok, installed it on Debian 11 via Flathub. It connects and I can start calls via dialing. But neither sound nor starting calls from contacts seem to work. 🙃
