<div>You are right. 200OK messages are also with private
IPs.</div>
<div>I think the problem is that </div>
<div>since I call dlg_bridge with Kamailio's own IP </div>
<div>It sends INVITE messages to itself first then it
routes INVITE msg to user location.</div>
<div>Because of this i see two record routes in the INTIVE
headers and 200 reply headers.</div>
<div><br>
</div>
<div> if (is_reply()) {</div>
<div> if(isbflagset(FLB_NATB)) {</div>
<div> if(is_first_hop())</div>
<div> set_contact_alias();</div>
<div> }</div>
<div> }</div>
<div><br>
</div>
<div>But according to this code in NATMANAGE block, it
only set contact if it is first hope.</div>
<div>Since these messages have two record routes, this
code block does not modify contact field</div>
<div>Am I right? or Am I missing something else?</div>

<p>dlg_bridge is not using the location table at

<p>Have you used set_contact_alias() for natted

<div>I am trying to

<div>But It seems that
Kamailio routes REFER

according to Contact
field of location table

<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></a><a>"sip:$param1"</a>,
<a></a><a>"sip:$param2"</a>,
<a></a><a>"sip:IP_ADDRESS_OF_KAMAILIO:5060"</a>);<br>

<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

<div>So it fails to
initiate a call.</div>
<div><br>
</div>
<div>How can I force
Kamailio to use Received
