J. Lennox: AUTHOR [+2]
The Session Description Protocol (SDP)  provides a general-purpose format for describing multimedia sessions in announcements or invitations. For many applications, it is desirable to establish, as part of a multimedia session, a media stream that uses a connection- oriented transport. RFC 4145, "TCP-Based Media Transport in the Session Description Protocol (SDP)" , specifies a general mechanism for describing and establishing such connection-oriented streams; however, the only transport protocol it directly supports is TCP. In many cases, session participants wish to provide confidentiality, data integrity, and authentication for their media sessions. Therefore, this document extends the TCP-Based Media specification to allow session descriptions to describe media sessions that use the Transport Layer Security (TLS) protocol .

Connection-Oriented Media Transport over the Transport Layer Security (TLS) Protocol in the Session Description Protocol (SDP)
This document specifies how to establish secure connection-oriented media transport sessions over the Transport Layer Security (TLS) protocol using the Session Description Protocol (SDP). It defines the SDP protocol identifier, 'TCP/TLS'. It also defines the syntax and semantics for an SDP 'fingerprint' attribute that identifies the certificate that will be presented for the TLS session. This mechanism allows media transport over TLS connections to be established securely, so long as the integrity of session descriptions is assured.
This document obsoletes RFC 4572 by clarifying the usage of multiple fingerprints.
