|
* 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)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 Focus. 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
