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
