        <div>Nice to hear from you again, you are always very helpful :)</div>
        <div>Unfortunately, I doubt that Microsoft would listen to my
          request, they're bending RFCs the way they like it, for
          example - using FQDN in 'Contact' field and no 'to' tag in
          this 487 reply. I assume it's quite safe to ignore this

                <div>My upstream carrier is replying back to CANCEL
                  request with a 487 Call Cancelled message that doesn't
                  have a 'to' tag in its headers. So, I'm getting these
                  errors in OpenSIPS logs:<br>

                <div>ERROR:dialog:push_reply_in_dialog: [487] reply in

                <div><br>
                </div>
                <div>But dialogs are closing correctly on BYE and I
                  don't see any dialogs hanging in any state when the
                  call is finished. Is it something I should be worried
                  about or can I just ignore this error? Is there any
                  way to avoid it by OpenSIPS script processing logic?
                  Maybe I need to call some function to fix this dialog?
