How to encrypt regular phone calls? (lemmy.zip)

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?

Agreed. It's a fun thought experiment. You have an acoustic tunnel. It may be transited over VoIP it may not. You can use that acoustic tunnel however you like, so implementing secure voice via audio is doable even if the underlying network turns it into VoIP

For what it's worth signal voice quality is much much much much much much much higher, because it can use more bandwidth, then cellular voice connections
