Ah, thanks for correcting me there. I knew that EA were involved at some level and I didn’t think to research that part of the post I was replying to, so I stand corrected, but I think the main point I was making is still valid, that the team that initially developed the game weren’t behind this re-release.
I’ve got my instance of matrix working with voice calls. It’s not built in, but it’s just another service in my compose file alongside the bridges I use to have my unified chat app.
I’m using coturn and it just works when doing voice and video calls with federated users.
I think I’ve seen people using jitsi as well, so it seems there are many options available
