  "abstract": "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. [STANDARDS-TRACK]",
