This article outlines the TCP/IP ports used by RightFax client applications and server components for proper communication across various environments. Understanding these port requirements is essential for configuring firewalls, network security, and interoperability with external systems like email gateways and databases.
RightFax relies on a range of TCP/IP ports depending on the version and module in use. Core services like FaxUtil, Enterprise Fax Manager, DocTransport, and Remoting APIs utilize specific port ranges. Many components also communicate via industry-standard ports such as 25 (SMTP), 443 (HTTPS), and 1433 (SQL Server).
Administrators should be aware of bidirectional communication needs and version-specific port changes. For instance, legacy ports 1052, 1053, and 1062 were deprecated after version 9.3. More recent releases (16 EP4 through 23.4) have standardized port usage around 10520–10522 and 34987–34988.

Additional Notes
Bidirectional communication is required for most connections. Unidirectional firewall rules must be tested carefully.
TCP/IP ports 1052, 1053, and 1062 are deprecated after version 9.3.
Port usage should always be verified during setup, upgrades, and firewall audits.
For FOIP port requirements, refer to the KB article on Brooktrout SR140/TR1034 integrations.
Use tools like Wireshark to identify additional port usage if not documented.
