Abstract:
The Session Initiation Protocol (SIP) supports the capability to
provide a reference to a specific rendering to be used by the UA 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 SIP Alert-Info header fields (and situations with
similar requirements) is defined in this specification.
This document normatively updates [RFC3261], the Session Initiation
Protocol (SIP): It changes the usage of the SIP Alert-Info header
field defined in the [RFC3261] by additionally allowing its use in
all provisional responses to INVITE (except the 100 response).
