The Session Initiation Protocol (SIP) supports communications across
many media types, including real-time audio, video, text, instant
messaging, and presence.  In its current form, it allows session
invitations, instant messages, and other requests to be delivered
from one party to another without requiring explicit consent of the
recipient.  Without such consent, it is possible for SIP to be used
for malicious purposes, including spam and denial-of-service attacks.
This document identifies a set of requirements for extensions to SIP
that add consent-based communications.  This memo provides information for
the Internet community.

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