SIP代理、SIP集群和媒体集群调研

修改OV500-master/portal/api/lib/OVS.php程序：
    function main($REQUEST) {
    
                $this->Hunt_Network_Addr = $this->request['Hunt-Network-Addr'];//在这行后面，主要修改这个地址为目标sip所在的kamailio服务器ip
        $this->Hunt_Network_PORT = 5063; 
        //update the target hunt network  
        $query = sprintf("select domain, contact, username, callid, socket from location where username = '%s';", $this->destination_number); 
        $this->writelog($query);
        $this->query('KAMAILIO', $query);
        $rs = $this->resultset();
        if (count($rs) >= 1) {
            $result = $rs[0];
            $socket_target = $result['socket'];//udp:11.12.117.200:5061
            //$index = strpos($socket_target, ':') ;
            $arr = explode(':', $socket_target);
            if (count($arr) == 3){
                $this->Hunt_Network_Addr = $arr[1];//substr($socket_target, $index + 1);   
                $this->Hunt_Network_PORT = $arr[2];
                $this->writelog("lyz get target, $this->Hunt_Network_Addr:".$this->Hunt_Network_PORT);
            }
        }else{
            $this->writelog("lyz get target, retun null");
	    }
        //ADD END.
        
    }
        
        代码中所有涉及bridge的地方进行替换修改：
        
        $this->Gateway_XML_incoming .= "\n <action application=\"bridge\" data=\"sofia/internal/" . $this->incomingcarrierdst . "@" . $lb . ":".$this->Hunt_Network_PORT. "\"/>";

修改OV500-master/portal/api/lib/OVS.php程序：

        //判断是否是会议模式，如果是，则直接返回报文就可以，会议模式以conf开头
        $index = strpos($this->destination_number, "conf_");
        if (false !== $index){
            $this->writelog("lyz add enter conference");
            $this->destination_number = substr($this->destination_number, $index + 5);

            $responce = $this->conferencecallxml(); 
            return $responce;
        }
         //add end
    }
