This document specifies how to use the Session Initiation Protocol
(SIP) to establish a Secure Real-time Transport Protocol (SRTP)
security context using the Datagram Transport Layer Security (DTLS)
protocol.  It describes a mechanism of transporting a fingerprint
attribute in the Session Description Protocol (SDP) that identifies
the key that will be presented during the DTLS handshake.  The key
exchange travels along the media path as opposed to the signaling
path.  The SIP Identity mechanism can be used to protect the
integrity of the fingerprint attribute from modification by
intermediate proxies.  [STANDARDS TRACK]

This document is a product of the Session Initiation Protocol Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
