Change your default calling app

Workspace Owners and Workspace Admins can default their workspace's phone icon to start calls via Slack or a supported third-party app.

To change your workspace's default app to another service, follow the steps below:

Step 1: Select and install a calling app

If you haven't already, choose a new calling service in Slack's App Directory and install the app for your workspace. You can find a list of our supported apps, and where to install them, here: Voice, video & screen sharing apps.

Note: Choosing a third-party calling app may require you to create an account with that service.

Step 2: Set the app as your workspace's default

Changing this setting will update the default calling app for all members:

  1. Visit your Settings page.
  2. Next to Calls, click Expand.
  3. Make sure the box next to Enable calling in Slack is checked.
  4. Select your preferred app from the drop-down menu. If the app isn't listed, make sure it's installed for your workspace (see Step 1 above).
  5. Click Save.
