<div class="moz-cite-prefix"><tt>Hi, Maciej!<br>
<br>
The behavior you are describing is exactly how OpenSIPS should
behave, so it's nothing wrong with your setup.<br>
The second affirmation is also right, if you want to change the
Contact header, you have to use topology-hiding, either the one
provided by the dialog module, or the B2B module.<br>
<br>
Best regards,<br>
