Peer-to-peer as it’s easier to get an app over getting a server. Must be libre software and E2EE too, obviously.
Mumble! You can host your own mumble server, I used to it for privacy over Discord. Getting people to use it is another challenge.
How is this peer-to-peer?
If you host the server it is. Which is really easy. Then you can do stuff to add security like adding an IP whitelist perhaps along with other things.
How’s it peer-to-peer when there’s a server?
Jami on desktop, not on phones yet:
Available only for desktop users for now, the new Push-to-talk feature offers a new effortless way to communicate: simply press a button for hands-free, instant, and convenient audio messaging. It’s like in the olden days of gaming when gamers would key bind the Push to talk feature to be able to talk when necessary.
So jami all the way, 🙂
