Technical Summary
This document describes private extensions to the Session Initiation
Protocol (SIP) that enable a network of trusted SIP servers to assert
the service of authenticated users. 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 service
identification model suitable for use between different trust
domains, or use in the Internet at large.
The document also defines a URN to identify both services and UA
applications. This URN can be used within the SIP header fields
defined in this document to identify services, and also within the
framework defined for caller preferences and callee capabilities to
identify usage of both services and applications between end UAs.
