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?

Not that I'm aware of phone calls traversed the cellular network and are uncrypted. Okay, well that's not exactly true. They are encrypted, but the cellular network has the decryption key. That way nobody on the air can listen to the call, but the cell company can record it.

Can't the signal be encrypted first by client and then sent to cellular network?

Yeah third party apps can do end to end encryption. It uses the data network and not the cellular network then though.

Google Fi on Android actually does run E2E on calls https://fi.google.com/about/end-to-end-encrypted-calls/

With audio encryption hardware, sure. Speak into that and feed its output to the mic on the phone

I think they are interested in a purely software solution

I think you're right. I know for a fact that I do not know of any, not for regular phone calls. Obviously if you want to use the internet and data, there's tons of options.

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

[–] [email protected] 1 points 8 months ago

I don't myself. So I am not sure.
