Title : Simpler Algorithms for Processing Alert-Info URNs

Abstract:
The "alert" namespace of uniform resource names (URNs) can be used in
the Alert-Info header field of Session Initiation Protocol (SIP)
requests and responses to inform a VoIP telephone (user agent) of the
characteristics of the call that the user agent has originated or
terminated. Based on the URNs in the Alert-Info header field, the
user agent must select an the best available signal to present to its
user to indicate the characteristics of the call. This document
describes a method by which a user agent's designer can, based on the
user agent's signals and their meanings, constructing a finite state
machine (FSM) to process the URNs to select a signal in a way that
obeys the restrictions given in the definition of the "alert" URN
namespace. In many situations, the resulting FSM is simpler and
faster than the previously described selection algorithm.
