</div>
<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>
