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. Working Group Summary The document complements work already performed in RFC 4474 for authenticated request identity, and forms an integral part of the chartered work in this area. There is consensus in the working group to publish this document. Document Quality The document has been well discussed by a significant number of members of the working group. Personnel The document shepherd for this document was Keith Drage. The responsible Area Director was Cullen Jennings.
