<div class="moz-cite-prefix"><tt>Hi Alexnader,<br>
<br>
The dialog is not destroyed by the received negative replies,
but when opensips forwards the negative reply back to the caller
side.<br>
<br>
So, in your case, the dialog will be ended when the 487 reply is
sent from OpenSIPS to FS. That following ACK (from FS) is not a
in-dialog ACK, but a hop-by-hop transactional ACK and it should
hit TM in your script. <br>
<br>
Regards,<br>

<div>I’ve a problem with negative replies retransmission. Dialog
is destroyed at this moment by upstream negative reply. How to
prevent this behaviour?</div>
