                Registration Event Package Extension for                    Session Initiation Protocol (SIP)                Globally Routable User Agent URIs (GRUUs)


   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.
