It was and still is maintained in a separate 10 * branch of the original SER.

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 27 * 28 * This file is part of Kamailio, a free SIP server. 29 * 30 * Kamailio is free software; you can redistribute it and/or modify 31 * it under the terms of the GNU General Public License as published by 32 * the Free Software Foundation; either version 2 of the License, or 33 * (at your option) any later version 34 * 35 * Kamailio is distributed in the hope that it will be useful, 36 * but WITHOUT ANY WARRANTY; without even the implied warranty of 37 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
