Technical Summary
Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) often act on the media plane, rather than just on the signaling path. This means that B2BUAs often act on the media path leading to separate media legs that the B2BUA correlates and bridges together. The document describes the behavior such B2BUAs can adhere to when acting on the media plane that uses a Secure Real-time Transport (SRTP) security context set up with the Datagram Transport Layer Security (DTLS) protocol.
