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
