Our verdict on Zetafax
Zetafax is network fax server software from Equisys for businesses that need centralized fax sending, receiving, routing, archiving, and application integration. It runs on Microsoft Windows and can be installed on physical or virtualized servers, including VMware and Microsoft Hyper-V environments. Its intended scope spans small and medium-sized businesses through larger organizations with multiple sites and higher-volume fax requirements. Microsoft-focused teams that still need controlled fax workflows are the clearest fit.
The product’s strongest area is workflow coverage across a Microsoft-centered environment. Users can send faxes through Outlook, Exchange Server, Exchange Online, SMTP servers, Microsoft 365 Apps, and Microsoft Office. Automatic inbound routing can use DID, DDI, and DTMF, while Fax over IP and T.38 gateway support complement fax modems and intelligent fax boards. Zetafax also connects with office scanners, multifunction peripherals, Lotus Notes, and ERP or CRM applications. Its Automation Toolkit extends application integration, and the electronic archive covers sent and received faxes.
Zetafax is positioned as a managed server product rather than a lightweight cloud-only fax service. The published offer includes a 30-day trial, while the licensing model is contact sales. That approach suits organizations that need server control, hardware options, virtualization, and established email or application workflows. Teams seeking a Windows-based, on-premises fax hub should consider it; teams looking for a simple browser-first service or a perpetual free plan should look elsewhere.
