Video calls
How it works
- 1
How do calls start?
From the room. A call inherits the membership and permissions of the channel or conversation it began in.
- Start from any channel or direct message
- Incoming-call notification with a ringtone
- Join from several devices at once
- 2
What is in a call?
Screen sharing, in-call chat, reactions, raise hand and noise suppression. Hosts get a lobby and controls.
- Lobby, mute, remove, transfer host
- End the call for everyone
What does encryption change?
In an encrypted room the media server forwards packets it cannot decode. Recording and dial-in would need decoding, so they are not offered there.

What it does not do
Fifty participants per media node is a design target, not a measured figure.
Finished recording files, dial-in, live captions, breakout rooms and transcription are not built.

FAQ
Questions
- All calls are encrypted in transit. In end-to-end encrypted rooms the media is additionally encrypted end to end, so the media server forwards streams it cannot decode.
- The system is designed and instrumented for fifty participants per media node, with scale-out beyond that as an operational step. That is a design target rather than a measured result.
- Only in managed rooms; recording would require decrypting media outside an encrypted room. The pipeline accepts recording jobs today; delivery of finished files is still being completed.
