    <p>Hello,</p>
    <p>from_tag and to_tag are actually crucial to match the invite and
      the bye records. call-id is usually unique per call, but by SIP
      RFC, a dialog is identified by (call-id, from-tag, to-tag) you
      have to use all three for matching.</p>
    <p>Back to the question, I don't think at this moment is any option
      to disable storing those values, c coding would be needed to make
      that optional.<br>

    <p>Cheers,<br>

          <div>I am using acc module for mainly duration. However,
            from_user, to_user, xcarrier etc are also important here.
            Was just curios if we can remove unnecessary columns someway
            since first insert is coming from acc_db_request.
            Alternatively, I can use sqlops. Please let me know.</div>

          Hello Z,<br>
          <br>
          please don't address individual persons if you write to this
          list, there are <br>
          many people subscribed. :-)<br>
          <br>
          The two tags are output important, as the acc module does not
          write complete <br>
          dialogs, only SIP transactions. You'll probably need them to
          do proper <br>
          accounting.<br>
          <br>
          Maybe you can explain what do you want to achieve?<br>
          <br>
          Best regards,<br>
          <br>
          Henning<br>
