The Internet Fax Feature must be disabled. (Cat II impact)

Excel, PowerPoint, and Word users can use the Internet Fax feature to send documents to fax recipients through an Internet fax service provider. If your organization has policies that govern the time, place, or manner in which faxes are sent, this feature could help users evade those policies.
