Is it even possible on android? Is there a FOSS dialer to optionally encrypt some phone calls (non voip) using a pre-shared key with other party?

With audio encryption hardware, sure. Speak into that and feed its output to the mic on the phone
do you know of any purchasable equipment? I’ve never been able to find any, then again I’m not versed in such things too much
I don’t myself. So I am not sure.
