7  * The initial version of this code was written by Dragos Vingarzan
8  * (dragos(dot)vingarzan(at)fokus(dot)fraunhofer(dot)de and the
9  * Fruanhofer Institute. It was and still is maintained in a separate
10  * branch of the original SER. We are therefore migrating it to
11  * Kamailio/SR and look forward to maintaining it from here on out.
12  * 2011/2012 Smile Communications, Pty. Ltd.
13  * ported/maintained/improved by
14  * Jason Penton (jason(dot)penton(at)smilecoms.com and
15  * Richard Good (richard(dot)good(at)smilecoms.com) as part of an
16  * effort to add full IMS support to Kamailio/SR using a new and
17  * improved architecture
18  *
19  * NB: Alot of this code was originally part of OpenIMSCore,
20  * FhG Fokus.

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