You can’t have e2e encrypted anything without identifying information about unique users.
SimpleX does it
No, it doesn’t. It has IDs for unique users, but tries to mitigate the risks by keeping a separate set of IDs to use with each contact. (This is like having a separate Matrix/Jabber/Signal/whatever account for each contact.)
SimpleX still has devices as users, you just don’t see it. If you’re just talking about some random PTT voice chat or something, I haven’t seen anything.
SimpleX does it but is missing PTT. Doesn’t Matrix do it too for server with optional registration.

Okay, that clarifies what you want, but SimpleX still doesn’t do what @just_another_person said. You seem to have misunderstood them.
Also, what’s with the downvotes? Do you expect people to spend their time trying to help you when you respond like that?
No offense, votes help sort comments and we’re moving off topic but your other comment is more useful, thanks again!
Email the devs, they’re really responsive
Great idea, actually found a similar issue on their GitHub.
