+ * 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.

+ * ported/maintained/improved by
+ * Jason Penton (jason(dot)penton(at)smilecoms.com and
+ * Richard Good (richard(dot)good(at)smilecoms.com) 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
