<p>Hi,</p>
<p><br>
</p>
<p>The To-header in the reINVITE is changed by the endpoint as far as I can see (if I understand your question correctly), i.e. something like this:</p>
<p>1) INVITE from endpoint to Kamailio</p>
<p>2) Kamailio performs uac_replace_from()</p>
<p>3) INVITE from Kamailio to endpoint (From-header modified)</p>
<p>4) dialogue goes on..</p>
<p>5) reINVITE from endpoint to Kamailio (To-header modified using data from modified From-header in step #3)</p>
<p>6) reINVITE from Kamailio to endpoint, ip-address becomes scrambled</p>

<p>Hello,</p>
<p><br>
</p>
<p>kamailio is not adding user=phone to To header by itself, it has to be something in the kamailio.cfg. What do you use to change the To? Or for changing From in initial INVITE?<br>
</p>
<p><br>
</p>
