Starting a Call
Calls let you switch from a text conversation to voice or video with team members. They are started from within a chat channel or direct message thread.
Call quality and in-call controls are being actively improved. Core functionality — starting, joining, leaving, and muting — works as described here.
Calls are available when Meetings is turned on for your workspace. If you do not see the Start a call button in a conversation, ask your administrator.
Before you begin
- Calls require a modern browser. Allow microphone access when your browser prompts. To share video, camera access is also required.
- Only people in the channel or direct message can join a call started there.
- You can set whether your microphone and camera start on or off in Settings, under Calls, by selecting Manage call preferences.
Starting a call from a channel or DM
- Open the channel or DM thread you want to call from. In a channel, you need to be a member.
- Select Start a call in the conversation header.
- The call opens in the chat window and you join it. A card in the thread says you started a call, and other participants are notified.
Joining a call
When someone starts a call in a thread you are part of, you are notified in either of these ways:
- An Incoming call window appears with Decline and Answer buttons.
- A card in the thread shows who started the call, with a Join call button.
Select Answer or Join call. The call opens in the chat window and connects you to the session. A call that has already ended cannot be joined.
