What is RightFax and which editions are current

RightFax — What is RightFax?

Purpose

Define RightFax, its current editions, and supported versions as of October 2025.

Applicability / Versions

Current maintenance versions: 24.4, 23.4, 22.2, 21.2.
20.2 entered sustaining maintenance in April 2025. 

Prerequisites

  • Windows Server and Microsoft SQL Server per the target version’s system requirements.

  • Telephony via FoIP SR140, boards, SIP trunks, or cloud telephony. 

What RightFax is

  • Enterprise fax server platform rebranded under “OpenText Fax,” still referred to as RightFax in many materials. 

  • Centralized send/receive, routing, archiving, reporting, and API/connector ecosystem for line-of-business apps. 

Editions (server types)

  • Business Server
    Single-server foundation for departmental or mid-size deployments. Upgradeable to higher editions. 

  • Enterprise Server
    Adds enterprise networking, security, and higher channel scale. Up to 1024 channels. 

  • Enterprise Suite
    Enterprise Server plus bundled modules for multi-server and broader integration needs.

  • Enterprise Integration
    Superset focused on deep application integration and connectors (e.g., SAP, Exchange), plus expanded modules. 

When to use which

  • Business Server: Single team or site.

  • Enterprise Server: Large single instance with higher concurrency and routing. 

  • Enterprise Suite: Multi-server estates standardizing add-ons. 

  • Enterprise Integration: ERP/EMR/CRM integrations and advanced automation. 

Validation

  • Confirm your version is within current maintenance (21.2, 22.2, 23.4, 24.4). 

  • Align OS/SQL with the version’s requirements before upgrades. 

Operations Notes

  • Size channels for peak load; separate rendering services for scale.

  • Consider hybrid cloud telephony from etherFAX to reduce PSTN complexity while retaining server control. 

Limits / Known Behaviors

  • FoIP stability depends on SIP/T.38 quality and SR140 configuration. 

Troubleshooting

  • Failed or slow FoIP calls → Inspect SIP/T.38 path and SR140 settings; validate trunk quality. 

  • Compatibility issues post-upgrade → Recheck OS/SQL prerequisites for your target version. 

Discrepancies (if any)

  • Some third-party materials mention “Business Integration” or “Enterprise Integration Suite.” Current SKU lists show Business, Enterprise, Enterprise Suite, Enterprise Integration, and Branch Office. Treat older names as legacy or bundle nomenclature. 

Change Log

  • 2025-10-10: Created.

  • 2025-10-10: Last validated.
