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?

Maybe I’m wrong, but I think it’s not the dialer app that operates the microphone, or at least it does not have total control over it, to record something and pass something else to the system.
