<p>Hello,</p>
<p>the mangler module does not have any idea of inbound/outbound directions, so you can use it for any of them.</p>
<p><br>
</p>
<p>Also, the nathelper module should have a function allowing to change the ip in the sdp, iirc.</p>
<p><br>
</p>
<p>On the other hand, if you use rtppengine for the calls, then the ips should be replaced by it.</p>
<p><br>
</p>
<p>Do not forget to use msg_apply_changes() in case you want those changes to be visible immediately in the configuration file.</p>
<p><br>
</p>
<p>Cheers,<br>
Daniel<br>
