Making calls in Slack

When you need to talk things out with a teammate, you can use Slack Calls to make a voice or video call 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 group DM or a channel and share your screen. Calls can have a maximum of 15 participants.
  • If an owner or admin has set a default calling app for your workspace, your call may start in another app.

Note: Slack Calls can only be used to make calls within Slack.
