Hello,

stun is recommended when the client properly implements it and does not sit behind a symmetric NAT (like linux box). For these cases you need to use server side nat traversal, look at nathelper/rtpptoxy or mediaproxy/mediaproxy.

Cheers, Daniel

Hello Users,

I tried a lot , My UAC's are Not Hungupping in Behind the NAT/Router

My SIP ip is 192.168.2.75 http://192.168.2.75 My Public IP is xx.xx.xx.xx

I didn't get any Bye request to SIP server, except the Bye all the other Messages are Requested to MY SIP Server

in openser.cfg i I'm using X-lites for testing in that RTP port 12222 NAT firewall ip is 192.168.2.1 http://192.168.2.1 Sip domain is xx.xx.xx.xx Sip proxy xx.xx.xx.xx ______________________________________________ modparam ("nathelper",rtpproxy_sock","udp: 192.168.2.75:12222 http://192.168.2.75:12222"

if(nat_uac_test("19")) { if(method=="REGISTER") { fix_nated_register(); force_rport(); setflag(6); } else {

                   if(method=="INVITE")
                   {
                     fix_nated_sdp("3")
                  };
                 fix_nated_contact();
      };
