The Session Initiation Protocol (SIP) is a simple protocol designed to enable the invitation of users to multimedia sessions. This document is a companion draft to draft-ietf-mmusic-sip-04.txt, which defines SIP but doesn't specify any security mechanisms other than possible protection by lower-level security mechanisms such as SSL. This leaves SIP transactions vulnerable to attack and this document aims to extend the SIP protocol to address such security considerations. This document is a product of the Multiparty Multimedia Session Control (MMUSIC) working group of the Internet Engineering Task Force Comments are solicited and should be addressed to the working group's mailing list at and/or the authors.
