When you need to talk things out with a teammate on the fly, you can use Slack calls to make a voice or video call to anyone in your workspace.

Note: Slack calls can only be used to make calls within Slack to other members of your workspace, and members from external organizations you’re sharing channels with.

What to expect

On any plan, a member can start a call with at least one other member from a direct message (DM).

A workspace must be on one of Slack's paid plans to start a call from a group DM or a channel.

Video calls are only available on your desktop.

Calls can have a maximum of 15 participants.

If a Workspace Owner or Admin has set a default calling app for your workspace, your call may start in another app.

Tip: For a list of keyboard shortcuts you can use when making calls, visit Slack calls: the basics.
