Abstract

This document describes private extensions to the Session Initiation Protocol (SIP) that enable a network of trusted SIP servers to assert the identity of authenticated users, and the application of existing privacy mechanisms to the identity problem. The use of these extensions is only applicable inside an administrative domain with previously agreed-upon policies for generation, transport and usage of such information. This document does NOT offer a general privacy or identity model suitable for use between different trust domains, or use in the Internet at large.
