    <font face="monospace">Hi Alexander,<br>
      <br>
      You actually have 2 options here:<br>
      <br>
      1) if you want to do that for all the calls, you can use
      E_DLG_STATE_CHANGED [1] event via the event route [2]. And check
      when the new dialog state is TERMINATED<br>
      <br>
      2) if you want to do it only for some calls, use the dlg_on_hangup
      hook [3] and have it set only for the calls you need.<br>
      <br>

      <div dir="ltr">Hi All.  I would like to invoke a web service when
        the call hangs up.  I'd like to send over to the web service
        items such as how long the calls lasted (milliseconds), etc.  I
        know how to invoke the web service, but where should I invoke it
        so it can send over those variables?<br>
        <div><br>

        <div>Thank you!</div>
