Now that Element have disabled the fallback SFU in call, it'd be good to have a setup guide, as this seems to be a FAQ.

Whenever I figure this out myself, I'll try to leave some docs documenting how I did it :)

For anyone else in the same boat I suggest checking out this post (even though it's a lil old): https://blog.kimiblock.top/2024/12/24/hosting-element-call/

"org.matrix.msc4143.rtc_foci": [
    {
      "livekit_service_url": "https://jwt.call.element.io",
      "type": "livekit"
    }
  ]

The same setup works with synapse. I also tried to replace the continuwuity binary by the tuwunel one in the exact same docker image with the exact same config and it worked.

If Element Call is not supported, how can I track the implementation progress?

Is Element Call supported? I tried to establish a call between Element Web (https://app.element.io) and Element X on Android but the call hangs indefinitely with "Waiting for media". I added this in `/.well-known/matrix/client`: ```json "org.matrix.msc4143.rtc_foci": [ { "livekit_service_url": "https://jwt.call.element.io", "type": "livekit" } ] ``` The same setup works with synapse. I also tried to replace the continuwuity binary by the tuwunel one in the exact same docker image with the exact same config and it worked.

Element call is supported, and works well on desktop clients:

Unfortunately, there is a subtle bug in the Simplified Sliding Sync service used by the Element X clients that means that some of the data that EC needs to do end to end encryption isn't sent. We haven't had time to track down and fix that bug yet, but we'll include an update in teh changelog when we have fixed it & verified the fix. I'll also send an update here if you're interested.
