+- Use `remove-csteamsinteorppolicy` to undo customization of global interoppolicy.

 Determines how calls are routed between Skype for Business and Microsoft Teams. This cmdlet s typically used by organizations that have users on both Skype for Business and Microsoft Teams and want to configure how calls are handled in their organization.
