When requesting and reporting dialog status in SIP, users often want
to know the status of a particular telephone instrument, rather than
the status of an Address of Record (AOR). The architecture of SIP
makes it difficult to obtain the status of a telephone instrument in
a way that is convenient for use in common situations, in particular,
in an organization's PBX. This document describes a method for
identifying which telephone instrument is making each registration
request that is convenient to deploy in PBXs. This information can
be used to obtain the status of individual telephone instruments.
Unfortunately, although the method works well in practice, it
violates separation of concerns by carrying instrument identification
information in an authentication-related field. This draft includes
a preliminary discussion of better ways to identify instruments.
