Voice, video and screen sharing apps

When you need to connect by voice or video call, or share your screen with your teammates, you have a few options in Slack. You can use Slack’s built-in calling feature or visit our App Directory to install a third-party calling app of your choice.

Tip: Owners and admins can set a default calling app, allowing all members of their workspace to quickly start a call by clicking the  phone icon.
