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

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
