IP FAX Relay, T.38 Support
Description
Because of their nature, Fax tones do not transmit well through IP networks, particularly when
compression is employed. To address this, the external network interfaces of the system support
T.38 protocol that defines the translation of analog fax tones to digital signals. When Fax tone is
detected on a port, the system will activate a T.38 Fax relay channel to the appropriate port.
