Obtaining and Using Globally Routable User Agent URIs in the Session Initiation Protocol
RFC 5627, “Obtaining and Using Globally Routable User Agent URIs in the Session Initiation Protocol”, is a Proposed Standard document published in October 2009 by J. Rosenberg. The canonical text is published by the RFC Editor.
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]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
