Re: SIP Diversion Problem

is there any reason why you do $(hfl(Diversion)[1]) instead of
$(hfl(Diversion)[$var(i)]) if I understand correctly?
it seems to me that you're always getting the same diversion value....

Also, you are constantly replacing value of $vn(new_div). Not sure why. $vn
is similar to $var and thus not a stack, replacing previous value with the
new one. The main difference between $vn and $var is $vn accepts null
values.

I'm obviously making some assumptions here, but I would try something
like this:

# reset target variable in private (pkg) memory
    $avp(new_div) = $null;

    # how many Diversion headers are present?
    $var(div_cnt) = $hdr(Diversion[*]);

    if ($var(div_cnt) > 0) {
        $var(i) = 1;
        while ($var(i) <= $var(div_cnt)) {
            # get the i-th Diversion header value and trim spaces, just in
case...
            $var(one_div) = $hdr(Diversion[$var(i)]){s.strip};
            $avp(new_div) = $var(one_div); // this avp will stack up the
value in LIFO - Last In First Out
            $var(i) = $var(i) + 1;
        }
    }

you will then be able to access index based values using $avp(new_div)[0]
or $avp(new_div)[*] to have a full comma separated list of values.
