Technical summary. Proxy servers play a central role as an intermediary in the Session Initiation Protocol (SIP) as they define and impact policies on call routing, rendezvous, and other call features. This document specifies a framework for SIP session policies that provides a standard mechanism by which a proxy can define or influence policies on sessions, such as the codecs or media types to be used. It defines a model, an overall architecture and new protocol mechanisms for session policies. Working group summary. There is consensus in the working group to publish this document. The early stimulus for this work came from discussions at the joint IETF/3GPP workshop held in San Francisco in January 2003. Document Quality This document was refined by several in-depth cross-area reviews. Personnel The document shepherd for this document is Keith Drage. The responsible Area Director is Robert Sparks.
