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.
