Hello,<br>
<br>
can you get the SIP trace with all the packets of such dialog
outside of the NAT router? It will help to see the headers and based
on that we may be able to provide a solution.<br>
<br>
Cheers,<br>
Daniel<br>

<div>Hello,<br>
<br>
</div>
I am running Kamailio behind NAT.<br>
<br>
</div>
Kanailio has a private IP and I am
relaying NAT to internet router.<br>
<br>
</div>
I am using:<br>
<br>
- #!define WITH_NAT<br>
- listen=udp:PRIVATE-IP:5060 advertise
PUBLIC-IP:5060<br>
<br>
</div>
- Patched RTP proxy including the advertise
option<br>
<br>
</div>
And everything goes fine. I can make calls and
have two way audio.<br>
<br>
</div>
The problem begins when the callee ends the
call. BYE is not received in Kamailio (caller)<br>
<div>
<div><br>
</div>
<div>I included the public IP using
"add_contact_alias" because
"set_contact_alias" was not adding the
public IP. I included this in in NATDETECT
(pre loaded router)<br>
</div>
<div><br>
if(is_first_hop()) {<br>
xlog("L_NOTICE","Metodo: $rm
\n");<br>
xlog("L_NOTICE","is first
hop\n");<br>
#set_contact_alias();<br>
if
(!add_contact_alias("PUBLIC-IP", "$Rp",
"udp")) {<br>
xlog("L_ERR", "Error in
aliasing contact $ct\n");<br>
send_reply("400", "Bad
request");<br>
exit;<br>
}<br>
}<br>
<br>
</div>
<div>I think the problem is related to
destination that BYE is sent by the vendor.
From what I see IP and port is taken from
advertised in contact (PUBLIC-IP and 5060).
<br>
The problem is that internet router changes
the source port.<br>
<br>
Contact:
<a class="moz-txt-link-rfc2396E" href="sip:999999999@PRIVATE-IP:5060;alias=PUBLIC-IP~5060~1"><sip:999999999@PRIVATE-IP:5060;alias=PUBLIC-IP~5060~1></a><br>
<br>
</div>
<div>--- Is it correcto to
add_contact_alias("PUBLIC-IP", "$Rp", "udp")
in order to received new transactions or
should I follow a different procedure???<br>
<br>
</div>
<div>Thank you<br>
<br>
