Change your default calling app

Team Owners and Admins can default their team’s phone icon to start calls via Slack or a supported third-party app.

To change your team'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 team. 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 team's default

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

  1. Visit your Team 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 team (see Step 1 above).
  5. Click Save.
