There are some application but a lot of them give as bad connection,noise,interrupt

@Laurent

everything is wrong with Signal. Starting with the fact that they have had no iOS developer for almost a year now. The android app is FULL of bugs, calls disconnect every couple of minutes, etc etc. Moxie doesn't listen to the community, PRs are turned down all the time, bug issues on github are closed because "it's never OWS's fault". Users are leaving Signal because they are frustrated to see bugs unsolved, PRs rejected, only ios and android supported (when they have explicitly rejected PR about ubuntu phones and they've said they don't plan on coding for any other platforms), bad community managment, and I could go on forever.

We need a serious company with a serious funds managment like Protonmail to do this kind of thing if we want it to be successful. Signal is for fanboys who don't understand that the world revolves around money, and you need developers to build stuff (more than just one developer on android and one for a browser extension).

The old GSM phone calls were all encrypted - some with weak encryption. Some internet calls may be encrypted (a part of the way), but still intercepted by the operator when needed. Encryption alone does not mean much. Sometimes it must be both strong and end-to-end.

Who is your adversary? A neighbor or the Russian empire?

Dear Jason, what's wrong with Signal ? https://whispersystems.org/

It only works from a smartphone, but that's not an issue for me at least. I have been using their app for messaging since a while and a made a few calls with it, perfectly fine. Sure, something with "ProtonMail" logo might feel more secure.

Looking for a way to conduct encrypted phone conversation similar to Google voice

It is a large feature to augument yes, but ive postulated this for post beta relaeses

-(voice-over-internet-protocol) dialing metric to allow browser voice calls via voice plugin for microphone

redact caller ID
