A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Session Initiation Protocol (SIP) emergency call back identification Author(s) : Christer Holmberg Filename : draft-holmberg-ecrit-emergency-callback-id-00.txt Pages : 12 Date : 2011-10-24 This specification define a new type of Globally Routable User Agent URI (GRUU) [RFC5627], called emergency GRUU (eGRUU). When a User Agent (UA) provides makes an emergency call, it can provide the eGRUU to a PSAP, which can then use it to make a PSAP callback call. The specification also defines a new URI parameter, "psapcb", which can be used to indicate that a URI can be used for PSAP callback calls. A registrar will provide the URI parameter as part of the generated eGRUU value. Later, when a PSAP makes a PSAP callback call the URI, including the "psapcb" URI parameter, can be used by SIP entities to identity callback calls.
