So what features do these bridges support? Does voice chat work? Can I share screen through them? Can I upload attachments?
I would love to switch to something open source, but communication with other people usually has to have the same thing on both ends.
Discord won because it offered more than mumble/teamspeak and did more and better than skype at the time and looks like even to this day. It's even better than slack and teams when it comes to resource usage.
