Hello!

Regarding the second and third question. I once did like this:

route
{
   route(checks);
   route(reqinit);
..
   route(class4);
}

route[reqinit]
{
   ....

   if (has_totag() && (uri == myself) && is_method("INVITE|ACK|BYE|UPDATE"))
   {
       if(match_dialog())
       {
           # sequential request -> obey Route indication
           if(is_method("BYE"))
           {
               t_on_reply("manage_reply_class4");
               xlog("[$ci] INFO BYE DIALOG_DID=$DLG_did DLG_lifetime=$DLG_lifetime \n");
               route(acc_stop);

           }
           else

                   t_relay();
                   exit;
               }
           }
           #loose_route();
           t_relay();
           exit;
       }
       if ( is_method("ACK") )
       {
           if ( t_check_trans() )
           {

       }
       xlog("[$ci] INFO No such dialog\n");

A few question;

Firstly

With mod acc and acc_cdr i see the default fields logged is only start_time, end_time, duration.

This is an actual entry logged.

start_time, end_time, duration
1515353126, 1515353135, 9.660000
Hello!

Regarding the second and third question. I once did like this:
Why is the duration 9.660000?

It seems wrong because it is more then the difference in time

1515353135 - 1515353126 = 9

Secondly

What is a reliable way to capture and log start time, answer time, and end time.
How do I get the duration info. a) start time to end time. b) answer to end time.

Is there an built in variable that store this info?

Thirdly

dialog events listed as:

event_route[dialog:start]
event_route[dialog:end]
event_route[dialog:failed]

There does not seems to be a event for answer so then how to be notified when a dialog is answered?

Regards
