Customize call settings for your workspace or organization

By default, the  phone icon is available for all members to make Slack Calls on your workspace or Enterprise Grid organization. There are a few ways to customize the voice and video call settings:

  • Show the phone icon to operate Slack Calls for everyone.
  • Hide the phone icon to turn off Slack Calls for everyone.
  • Set the phone icon to operate a different third-party calling app.

Keep in mind: Any Owner or Admin can manage workspace call settings and any changes will impact all members. Members cannot customize their call settings individually.
