Engage can also summarize documents and show sender information and an overview to help with review. ETHERFAX offers virtual fax numbers, inbound and international faxing, and a web API for document delivery. Listed integrations include Epic, Hyland OnBase, Canon, Ricoh, Xerox/Lexmark, Microsoft 365, Google Workspace, and Microsoft Teams. Security measures include encryption, two-factor authentication, and in-network routing.
