By default, your company anthem is a round of applause but some companies have a song in mind, or would rather a different sound such as a bell ding or a sales gong sound.
By default, you must have Admin permissions on OneUp to change your company settings.
Changing your company anthem
Select Manage in the main navigation menu, and then, Customize OneUp.
Navigate to the Automations page.
