Hi Ravi
Thanks . after i saw log evenet on UAC . i do not sure that ACK message from CALLER can not reach CALLEE so,after about 30 second CALLEE HANGUP or not so i put some log .
in this case i do not sure also that my ADSL ROUTER(A) in front openser server is OK to handle SIP messages or not.
i think but do not test concept. that ACK message from CALLER is not handle propery . any idea
from CALLER UAC1(janny) file

Hi Somsak The Same issue is faced ,
The in ur FireWall/router, ... In Router , openSER system is in DMZ mode, i'm Sure , Even through u did like that...
ADSL(A) Router is mis place the HeaderContact
Change the Router... with Support the SIP with NAT... Cisco , Linksys, Zoom,
can u check the Dialog file UAC ( x-lite 3.0) ... U can see there for invited... Ack and Bye Contact Header is misplacing into the private ip,,,,,,
Keep OpenSER direct to the Internet ( for testing ) ............ it will work finely........
sorry i can not direct INTERNET connect

Dear All
i will setup openser behind NAT like these
OPENSER ---> ADSL ROUTER(A) <---> INTERNET <---> ADSL ROUTER(B)<-- UAC(1) <-- UAC(2)
for UAC to talk each others in the same network with OPENSER server and try to REGISTER AND INVITE IT OK .
but if i use UACs that located behind ADSL ROUTER(B) for REGISTER it OK when UAC(1) INVITE UAC(2) it RING and session established can heard sound
but after about 30 second the CALLEE UAC(2) is HANG UP while CALLER UAC(1) still show established
i saw some mail said that the problem may occour from ADSL ROUTER ITSELF (AGL problem)or some say that ACK problem. if i connect UAC(1) and UAC(2) through ADSL ROUTER(B) to iptel.org and i use UAC(1) INVITE UAC(2) it work no problem for 30 second disconnection . also if i use UAC(1) and UAC(2) conect to iptel.org through ADSL ROUTER(A) no problem . AT this point can I CONCLUDE THAT BOTH ADSL ROUTER NO PROBLEM FOR SIP CONNECTION. is it TRUE ??
Next i saw from LOG file it seem no ACK MESSAGE and error like these -- LOG FILE ------------- ERROR: tcp_blocking_connect: poll error: flags 18 ERROR: tcp_blocking_connect: SO_ERROR (111) Connection refused ERROR: tcpconn_connect: tcp_blocking_connect failed ERROR: tcp_send: connect failed
for simply NAT testing i use openser.cfg like these
---------- OPENSER.CFG --------- if (!method=="REGISTER") record_route(); if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); };
if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); };
if (uri==myself) { if (method=="REGISTER") { if (!www_authorize("infowavenet.com", "subscriber")) { www_challenge("infowavenet.com", "0"); exit; }; fix_nated_register(); save("location"); exec_msg("cat >> /tmp/test"); exit; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using our USRLOCDB if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; append_hf("P-hint: usrloc applied\r\n"); }; route(1); }
route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP fix_nated_contact(); if(method == "INVITE") { fix_nated_sdp("3"); } if (!t_relay()) { sl_reply_error(); } else { exec_msg("cat >> /tmp/test");} exit; }
MY QUESTION:
- can openser server is BEHIND NAT ADSL ROUTER and receive Call from
UAC from other NAT ROUTER .
- if so what the problem that CALLEE HANGUP every 30 seconds
( i use XLITE v.3 for UAC )
- if it possible can you fix openser.cfg that work for this situation
Best
