Registration Event Package Extension for Session Initiation Protocol Globally Routable User Agent URIs
RFC 5628, “Registration Event Package Extension for Session Initiation Protocol Globally Routable User Agent URIs”, is a Proposed Standard document published in October 2009 by P. Kyzivat. The canonical text is published by the RFC Editor.
Abstract
RFC 3680 defines a Session Initiation Protocol (SIP) event package for registration state. This package allows a watcher to learn about information stored by a SIP registrar, including its registered contact.
However, the registered contact is frequently unreachable and thus not useful for watchers. The Globally Routable User Agent URI (GRUU), defined in RFC 5627, is a URI that is capable of reaching a particular contact. However this URI is not included in the document format defined in RFC 3680. This specification defines an extension to the registration event package to include GRUUs assigned by the registrar.

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.
