Re: SIP Diversion Problem

remove_hf removes all the identified header (as found in textops docs: "Remove
from message all headers with name “hname”. " ),
so why are you removing headers inside the loop? The 1st time
remove_hf("Diversion"); should be enough

Why not just do:

            remove_hf("Diversion");

$var(i) = 0;

while($var(i) < $hflc(Diversion) ) {

            $vn(new_div) = $(hfl(Diversion)[1]);
            $var(i) =  $var(i) +1;
         }

Atenciosamente / Kind Regards / Cordialement / Un saludo,
