 * Author
 * 	Erik Eliasson, [e-mail]
 * Purpose
 *  If a 100rel Voip server is used, it will send a
 *  183 session progress reliably before the 180
 *  ringing is transmitted. This is so that authentication
 *  is done before the phone starts ringing. We must
 *  have mutual authentication before the phone starts
 *  ringing to avoid ghost ringing when Alice policy
 *  does not accept Bob's information.
