  * The initial version of this code was written by Dragos Vingarzan
  * (dragos(dot)vingarzan(at)fokus(dot)fraunhofer(dot)de and the
  * Fruanhofer Institute. It was and still is maintained in a separate
  * branch of the original SER. We are therefore migrating it to
  * Kamailio/SR and look forward to maintaining it from here on out.
  * 2011/2012 Smile Communications, Pty. Ltd.
  * ported/maintained/improved by 
  * Jason Penton (jason(dot)penton(at) and
  * Richard Good (richard(dot)good(at) as part of an 
  * effort to add full IMS support to Kamailio/SR using a new and
  * improved architecture
  * NB: Alot of this code was originally part of OpenIMSCore,
  * FhG Fokus.

  * Thanks for great work! This is an effort to 
  * break apart the various CSCF functions into logically separate
  * components. We hope this will drive wider use. We also feel
  * that in this way the architecture is more complete and thereby easier
  * to manage in the Kamailio/SR environment
