<p>Hello,</p>
<p>can you send the ngrep trace for such case? I would like to look
at the headers to understand properly what do you mean.</p>

<div dir="ltr">Hello
<div><br>
</div>
<div>I am trying to implement click 2 call functionality on
Kamailio with dlg_bridge.</div>
<div>But It seems that Kamailio routes REFER messages to devices
according to Contact field of location table instead of
Received field. </div>
<div>But if the the IP in the Contact field is private REFER
messages are failing so </div>
<div>does the dlg_bridge.</div>
<div><br>
</div>
<div><br>
</div>
<div>I called dlg_bridge in the config like this:</div>
<div><br>
</div>
<div>dlg_bridge(<a>"sip:$param1"</a>, <a>"sip:$param2"</a>,
<a>"sip:IP_ADDRESS_OF_KAMAILIO:5060"</a>);<br>
</div>
<div><br>
</div>
<div>It rings the device in $param1 but after answering on that
device</div>
<div>Kamailio fails to send REFER if the Contact field for that
device is Private IP.</div>
<div>So it fails to initiate a call.</div>
<div><br>
</div>
<div>How can I force Kamailio to use Received field for REFER
messages instead of Contact field?<br>
</div>
<div><br>
</div>
<div>Thanks</div>
