The SBC stores an internal binding between the AOR and the original contact of the user. It includes: •The Contact URI sent by the UA in the REGISTER message, the originating IP Address and port, the user’s realm, and the Contact URI sent to the registrar •The userinfo in the Contact URI sent to the registrar includes the original userinfo from the UA, followed by an encoded cookie Correct answer: C
