Title: Obtaining and Using Globally Routable User Agent (UA) URIs (GRUU) in the Session Initiation Protocol (SIP)

Several applications of the Session Initiation Protocol (SIP) require a
user agent (UA) to construct and distribute a URI which can be used by
anyone on the Internet to route a call to that specific UA instance. A URI
which routes to a specific UA instance is called a Globally Routable UA URI
(GRUU). This document describes an extension to SIP for obtaining a GRUU
from a server, and for communicating a GRUU to a peer within a dialog.
