Bluetooth for phone calls

[Stray]

I've had my PinePhone Pro for a few months, and tinker with it on occasion, mostly trying to get my Bluetooth headsets to work with it. I can get the phone to output media, and even the recorder does pickup the microphone when I set the audio profile to HFP. However, when I make a phone call, it reverts back to using the phone's speaker and microphone. The past 2 days I have been really trying hard to force it, with the help of ChatGPT, and deciphering the differences it was advising me to do to the device (such as telling me to restart Pipewire service using systemctl when it should be rc-service in the case of using PostmarketOS). I have searched, and thought I would get the PineBuds, but I don't want to get them if it's not going to work, considering I don't really like earbuds, but I would deal with it if it worked. In my searches, I have seen a lot of people are happy with their PineBuds, but they all mention just media playback, no mention of making phone calls (unless I'm not searching in the right places?) I've been using it lately just as a glorified music streamer connected directly to my trucks aux input, but I would actually like to use it, as a phone, and Bluetooth connectivity is very important to me as I am a truck driver, and spend most of my day driving. A wired headset does work as it should, but I would much rather not have a wire dangling limiting my maneuverability, or having the wire in my field of view (I have my existing phone on a mount on the top shelf above the windshield, so if I daily the PinePhone, it would go in that spot).

So, my question is, are there any reports of working Bluetooth headsets that work for calls on any OS? I have tried PostmarketOS (with plasma-mobile, as Plasma is my preferred DE), Mobian (Phosh and Plasma), Arch (Phosh), Ubuntu Touch, Manjaro, and the factory installed SailfishOS (although, not very thoroughly as for some reason or another it won't accept my APN settings for AT&T, so that was a quick jump off)
