Hi Bogdan,
Goodmorning,
Please forgive in My english,..........
I install the openser server ( with public ip as xx.xxx.xxx.xxx. ) and the
System ip ( private ip openser) is 192.168.2.2 which is located In some
other place for UAs. And SIP_Domain as xx.xxx.xxx.xxx.
I installed the X-lite 3.0 and testing with that only...
Missed calls and Ignore calls are working fine........Here ACK is working,
When the softphone Rings , and lefted up , after 32 seconds the callee is
hunging ups and Caller is still in establishing the call ( not hung up)
Problem in , After the Invite request send , then it will to send ACk to
callee , to maintain the session alive ,
For example :- UA1 ( caller) -------------------> UA2 (callee )
::::::::::::::-----------> Both are in OutSide the NAT , in other network
)
Here Callee is Hungs up the calls automaticall,
IS the Problem in Router logic or in Router (Switches ) where is openser
located , or where X-lite is there.
Router ( switches) is stoppning the ACK ,
Bogdan, Help in this ,, here is my openser.cfg......
