I record all my calls with OBS because I know sometimes my mind drift off especially when people are going off topic for a while or part of the call is not relevant to me and I want to be able to get back to it if I missed something important.

I have a systemd timer that clean files older than 24h at startup because the point is not to archive content without consent.

If I ever can't do that I would just use an usb3 screen capture card and record from a second device.
