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. Working Group Summary The WG path of this document was reasonably short and efficient. Several technical comments were made during reviews and all were resolved with consensus. There is consensus in the STRAW WG to publish this document. Document Quality The guidelines and procedures in the document is based on input and experience from the implementer community. Personnel Christer Holmberg (email@example.com -- STRAW WG co-chair) is the shepherd. Ben Campbell (firstname.lastname@example.org) is the responsible Area Director.
