<p>Hello,</p>
<p>dlg_bridge is not using the location table at all, because it has
to use the contact from 200ok of INVITE.</p>
<p>Have you used set_contact_alias() for natted 200ok received for
INVITE?</p>
<p>Cheers,<br>
Daniel<br>

<div dir="ltr">Hello

</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 moz-do-not-send="true">"sip:$param1"</a>,
<a moz-do-not-send="true">"sip:$param2"</a>, <a
moz-do-not-send="true"><a class="moz-txt-link-rfc2396E" href="sip:IP_ADDRESS_OF_KAMAILIO:5060">"sip:IP_ADDRESS_OF_KAMAILIO:5060"</a></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>
