While it is possible to transmit highly sensitive documents using traditional telephony encryption devices, secure fax on the Public Switched Telephone Network (PSTN) was never widely considered or prioritized. This was mainly because of the challenges involved with malevolent physical access to telephony equipment. As real-time communications transition to IP networks, where information might potentially be intercepted or spoofed, an appropriate level of security for fax that offers integrity and confidentiality protection is vital.

UDP Transport Layer (UDPTL) over Datagram Transport Layer Security (DTLS)
This document specifies how the UDP Transport Layer (UDPTL) protocol, the predominant transport protocol for T.38 fax, can be transported over the Datagram Transport Layer Security (DTLS) protocol, how the usage of UDPTL over DTLS is indicated in the Session Description Protocol (SDP), and how UDPTL over DTLS is negotiated in a session established using the Session Initiation Protocol (SIP).
