[Kamailio-Users] NAT traversal

[BERGANZ François]

With the STUN server, I can ring the NATed phone!

But, I can hear the NATed phone with the public phone, and NATED phone can’t hear the public phone!

If I install my stun server, when I will do save("location"), it will save the good IP and port in the db?

yes, because UAs will know their public IPs using STUN.


you can also use NATHELPER Module in KAMAILIO to fix NAT e.g

 if(nat_uac_test("1")) {
           fix_nated_register();

               fix_nated_contact();

            force_rport();

    } 









Thanks,

if the phones are not behind symmetric NAT and they have STUN support,
then you have to install a stun server or use a public one and nothing
else to do on your sip server. It is so called client-side NAT traversal.
