[OpenSIPS-Users] Regarding opensips-1.11 variable use .

[Benjamin Cropley]

Sorry - just realised what you mean. You're saying do it like..

route{
    # set vars back to null/init them..
    $var(c)="";
    $var(d)="";
    $var(e)="";
    $var(f)="";

    if (method=="INVITE") {

        if(is_present_hf("X-Info")){
            # assign values to vars...
            $var(c)=$hdr(X-Info);
            $var(d)=$(var(c){s.select,2,;});
            $var(e)=$(var(c){s.select,3,;});
            $var(f)=$(var(c){s.select,4,;});
        }

        #Set the flag for counting the dialogs. We user flag=4 for counting
dialogs
        setflag(2);
        setflag(4);
        xlog( "L_NOTICE", "CallCenter_Info & $ci,$var(c) \n" );
        xlog( "L_NOTICE", "3CLogicCDR & $ci,$fU,$oU,$rd \n" );
        xlog("L_NOTICE", " Source IP ($si) :  method ($rm) r-uri ($ru) :
callID $ci \n");

    }
}
