Calls that start where the conversation already is

From the room. A call belongs to the channel or conversation it began in, which means it inherits that room’s membership and permissions instead of needing a second invitation list. Incoming calls ring with a notification, and you can join from more than one device at once.

• Start from any channel, direct message or group
• A Calls surface showing what is live and what is ringing, with join, invite, manage and end
• Incoming-call notification with a ringtone
• Join from several devices at the same time

Screen sharing, in-call chat that survives into the room afterwards, reactions and raise hand, background blur and noise suppression. Hosts can mute, remove or promote a participant, and a lobby holds people outside until they are let in.

• Screen sharing on web and desktop
• In-call chat, reactions, raise hand
• Background blur and noise suppression
• Lobby, host transfer, mute, remove, end call for everyone

In an end-to-end encrypted room the media is encrypted with keys the media server does not hold, so it forwards packets it cannot decode. That is the point, and it is also why two features are not offered there: recording and telephone dial-in would both require decoding the media somewhere outside the room, and doing that quietly would make the encryption a decoration.

• Media encrypted end to end in encrypted rooms
• No recording and no dial-in in encrypted rooms, deliberately
• Managed rooms keep recording and, later, SIP dial-in
