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

[Benjamin Cropley]

the value of script variables persists over any given OpenSIPS process.
Therefore, to ensure the value is null on every entry to the route (if a
subsequent packet is recieved on the same process) you must set the value
back to Null before the route is exited.

eg..
route{
    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");

        # set vars back to null..
        $var(c)="";
        $var(d)="";
        $var(e)="";
        $var(f)="";
        exit;
    }
}

I think this feature will have existed in both 1.6 and 1.11 (see
https://www.opensips.org/Documentation/Script-CoreVar-1-6#toc1 and
https://www.opensips.org/Documentation/Script-CoreVar-1-11#toc1). Maybe
something else is going on to make it 'work' in 1.6?
