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. [STANDARDS TRACK]
