+ * 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.

+ * 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
