[OpenSIPS-Users] $DLG_lifetime but in ms

[Ben Newlin]

A few people have mentioned this but I haven’t seen a response. Why do you have to do this conversion in the script? The call duration in ms is already included by default in every CDR. We are only talking about rounding here, why wouldn’t your rating application do that for you? That’s much less complex than adding an entirely new field just so OpenSIPS can do the rounding.

Hi Marcin,

Using math_ceil on $DLG_lifetime wont work as it returns seconds not
ms.

As for your other suggestion I am doing something similar just not sure
its the most efficient I am using get_accurate_time would $ts$Tsm be a
better approach,


at 200OK in onreply route

    if ($rs == 200) {
        get_accurate_time($var(now_s), $var(now_us));
        $dlg_val(start_s) = $var(now_s);
        $dlg_val(start_us) = $var(now_us);
    }

then on BYE

if (is_method("BYE")) {
    get_accurate_time($var(end_s), $var(end_us));
    ts_usec_delta($(dlg_val(start_s){s.int}),
$(dlg_val(start_us){s.int}), $var(end_s),  $var(end_us) ,
$var(billed_duration));
   $var(end_us) , $acc_extra(billed_duration)\n");
    math_eval("$var(billed_duration) / 1000000",
$var(billed_duration));
    math_ceil($var(billed_duration),$var(billed_duration));
    $acc_extra(billed_duration) = $var(billed_duration);

## Rate the call

    math_eval("$acc_extra(c_price) / 60 * $acc_extra(billed_duration)",
$var(c_cost));
    math_eval("$acc_extra(v_price) / 60 * $acc_extra(billed_duration)",
$var(v_cost));
    $acc_extra(cost) = $var(c_cost);
    $acc_extra(v_cost) = $var(v_cost);
}

Thanks.
