Making calls in Slack
When you need to talk things out with a teammate, you can use Slack Calls to make voice or video calls within Slack to anyone in your workspace.
What to expect
- On any subscription, you can start a voice or video call with at least one other person from a direct message (DM).
- On the Standard, Plus and Enterprise Grid subscriptions, you can start a voice or video call from a DM or a channel and share your screen. Calls can have a maximum of 15 participants.
- Owners and admins can set a third-party calling app as a default calling app. If this is the case in your workspace, clicking the phone icon may start your call in another app.
Tip: You can manage your preferences to always join Slack Calls with your audio muted and automatically set your status to 📞 On a call when you're on a call.
