<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText"> our kamailo has 2 IPs, a public (87.x.x.x) and a private (192.168.1.1). It is listening on all of them. For all calls it listens on the public IP but for some calls I need to forward the incoming INVITE to a server in the private network
so I do a " force_send_socket(privateip:port)" before the route that forwards the INVITE to the server in the private network and that works.<br>
<br>
But then when the server in the private network replies with 302 I have to contact the servers inside the Contact header using the Public IP now so I do this hoping that it will switch back to the public IP:<br>
<br>
if (t_check_status("302")) {<br>
force_send_socket(PUBLIC_IP:5060);<br>
get_redirects("*");<br>
t_relay();<br>
}<br>
<br>
But it stays in the private, so the INVITEs to the servers inside the Contact header are sent from the Private IP and they are blocked.<br>
<br>
This would be the flow:<br>
customer INVITE -> kamailio(publicIP)<br>
kamailio (publicIP) 100 trying -> customer<br>
<br>
kamailio(privateIP) INVITE -> Server(privateIP)<br>
Server(privateIP) 302 redirect -> kamailio(privateIP)<br>
kamailio(privateIP) ACK -> Server(privateIP)<br>
<br>
after I would like this to happen<br>
<br>
kamailio(publicIP) INVITE -> Server1(publicIP)<br>
but instead this happens:<br>
<br>
kamailio(privateIP) INVITE -> Server1(publicIP)<br>
<br>
how can I switch back to the public IP to continue with this call flow?<br>
thank you<br>
