Technical Summary This document describes a Datagram Transport Layer Security (DTLS) extension to establish keys for secure RTP (SRTP) and secure RTP Control Protocol (SRTCP) flows. DTLS keying happens on the media path, independent of any out-of-band signalling channel present." Working Group Summary There was a discussion about which in band keying mechanism should be used; it is captured in draft-ietf-sip-media-security-requirements. There was rough consensus for this solution. Document Quality There were indications by vendors that they will implement this solution. One vendor has shipping product with this, another has code used at interop events. Pasi Eronen did a good review during the WGLC that helped with improving of the document. He is mentioned in section 10 of the document (Acknowledgments) Personnel Roni Even is the document shepherd. The responsible area director is Cullen Jennings.
