Technical Summary 

Several applications of the Session Initiation Protocol (SIP) 
require a user agent (UA) to construct and distribute a URI 
that can be used by anyone on the Internet to route a call to
that specific UA instance. A URI that  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 registrar and for communicating a GRUU to 
a peer within a dialog.
