FoIP: The Overlooked MSP Opportunity, Many businesses still rely on fax to send and receive legally binding orders, insurance documents, and compliance paperwork

“If our fax or email system fails, that’s a catastrophe—we lose connection to our customers and orders stop coming in.” — Martin Hager, Founder & CEO, Retarus

Spring 2025 has been dominated by AI, cybersecurity, branded calling, and POTS replacement. But in this special Technology Reseller News podcast, we return to a foundational—and often forgotten—technology that continues to power mission-critical communications: fax.

Martin Hager, CEO of Retarus, joined Doug Green to discuss how the Munich-based cloud communications company was recently named a Leader in the IDC MarketScape for Worldwide Digital Fax Solutions—the only European provider to earn that distinction.

“Fax” may still conjure images of curling thermal paper and screeching machines, but Hager wants the channel to see it for what it is today: FoIP—Fax over IP—highly secure, server-to-server communication trusted by the world’s largest enterprises. With over 700 million fax pages sent annually through Retarus’ privately run global data centers, the company plays a critical role in industries ranging from finance to healthcare to manufacturing.

Why should MSPs and service providers care about fax in 2024? As Hager explained, a 1% improvement in fax reliability can save large enterprises hundreds of thousands of dollars in administrative costs, regulatory penalties, and customer churn. One client lost $860,000 from a single failed fax tied to a regulatory deadline.

Many businesses still rely on fax to send and receive legally binding orders, insurance documents, and compliance paperwork. With analog lines disappearing and traditional fax servers aging out, there’s a massive opportunity to consolidate and modernize fax infrastructure using FoIP.

More than 80% of Retarus’ business flows through the channel, and Hager says it’s an easy upsell for MSPs and agents already providing voice or UCaaS services. Whether it’s a dentist office, a healthcare network, or a manufacturer, fax remains a critical link in business operations. Retarus’ solutions offer full delivery traceability, SOC 2 and ISO 27001 compliance, and direct integrations with enterprise apps and multifunction devices.

With a simple conversation—”How do you send orders?”—partners can uncover opportunities that deliver both operational improvements and recurring revenue.
