    Riot does not have voice chat rooms with PTT or voice activation, it's primarily a chat app like Slack, and not an alternative to Teamspeak or Mumble.

    It's primarily a text chat app with bridges to many others. You could have a Jitsi widget to have a chat-room, but it's not the same, nor is it a core feature.
