Hi Daniel,

Yes, transaction is on the final response - fro INVITE you want to account when the call was accepted, not when it was dialed. If you want for the BYE to account when the request was received, use extra accounting to store the timestamp (ms also) of receiving the BYE (via script operations). When you correlate the INVITE with the BYE, you will calculate the duration from the 200 OK INVITE to the BYE request.

Or much simpler just use dialog based accounting which is already doing this.

Hi Bogdan

So on transaction accounting, the record is written after transaction receives final response. So it's not written as soon I receive BYE, but when I receive the 200OK of the BYE.

My customer is complaining that the call is taking 200ms more and our system is charging 1 sec more than on his billing. On million calls, this is generating a some thousands difference.

Thanks for the information!

Regards

    Hi Daniel,

    There are 3 types of accountings in OpenSIPS - per message, per
    transaction, per dialog.

    For the per message, it is clear :) . When doing per-transaction
    accounting, the ACC record is written when the transaction is
    completed with a final response (>=200) on the UAS side (towards
    caller). For the dialog based accounting, the time reference (for
    ending the call) is the reception of BYE request; still the CDR is
    written on the BYE final reply (as OpenSIPS allows you to collect
    CDR info from the BYE replies too).

    Hi Alex

    I'm having a billing problem from receiving BYE to 200 OK is
    taking more than 500ms. If BYE is accounted when it's received,
    great!

    Are you absolutely sure it works this way?

    Thanks

        My understanding is that this is a rather simple module
        without sophisticated state componentry, and that it logs
        things immediately as received, in the same iteration of
        message processing.
