Re: [Kamailio-Users] NAT traversal

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! àI just do lookup("location") and t_relay() is the problem comes from here?

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, Asim Cordialement, BERGANZ François http://www.acropolistelecom.net Pensez à lP'Environnement, n'imprimez ce mail que si nécessaire. -----Message d'origine----- De : Daniel-Constantin Mierla [mailto:miconda@gmail.com] Envoyé : vendredi 20 février 2009 10:22 À : BERGANZ François Cc : users(a)lists.kamailio.org Objet : Re: [Kamailio-Users] NAT traversal Hello, On 02/20/2009 10:03 AM, BERGANZ François wrote: 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.
