Hi,<br><br>More ideas:<br><div>- store the original From-Header in a Dialog-Parameter in order to replace the &quot;From&quot;-Header in subsequential requests (e.g. the uac-Module stores this in the RR-Headers, would be nice to store this in a Dialog-Parameter instead)</div>

<div>- validate subsequential &quot;Routes&quot; by comparing them with the defined Route in the original request?</div><div><br></div><div>Just some ideas,</div><div>Carsten<br><div><br></div></div>
