speaker mode + separate device to record.

Either that or use a computer to do the call and record using software on the computer.

I don't know how the latter is done but I know many companies do that.

just patch inputs and outputs to audacity (or your recording software of choice). for pipewire theres helvum[0] or qpwgraph[1]. for JACK there's Catia[2].

Can't one stick a recording device between the headphone and phone?

[Zigurd]

If you have a headphone jack and a splitter that could work. I do not know of any "two sided" Bluetooth devices that could sit between a phone and headset.

Yes, I’ve read that this is what most reporters do. There are a number of devices built for it. I’ve never used any so have no recommendations.
