URNs for the Alert-Info Header Field of the Session Initiation Protocol
                                 (SIP)
                  draft-ietf-salud-alert-info-urns-13

Abstract

   The Session Initiation Protocol (SIP) supports the capability to
   provide a reference to a specific rendering to be used by the UA as
   an alerting signal (e.g., a ring tone or ringback tone) when the user
   is alerted.  This is done using the Alert-Info header field.
   However, the reference (typically a URL) addresses only a specific
   network resource with specific rendering properties.  There is
   currently no support for standard identifiers for describing the
   semantics of the alerting situation or the characteristics of the
   alerting signal, without being tied to a particular rendering.  To
   overcome these limitations and support new applications, a new family
   of URNs for use in Alert-Info header fields (and situations with
   similar requirements) is defined in this specification.

   This document normatively updates RFC 3261, which defines the Session
   Initiation Protocol (SIP): It changes the usage of the Alert-Info
   header field defined in RFC 3261 by additionally allowing its use in
   all provisional responses to INVITE (except the 100 response).  This
   document also permits proxies to add and remove header field values
   from the Alert-Info header field.
