Hello,
openser does not reply with 481 Call Leg/Transaction Does Not Exist in
any circumstances. This is created by the gateway which has no active
call matching the dialog attributes in BYE.
What do you mean by "unstable and almost hanged"? No more CPU? Memory?
No message forwarding? Any error logs?
Cheers,
Daniel

I am using sipp to test the openser with the following result. It
will create message 481 after a certain traffic. In what conditioin
that openser will send 2 BYE to CISCO? When I increase the concurrent
call to about 50, the system becomes unstable and almost hanged. I am
concerning about the real loading of the openser. Does anyone can
help me?
--------------my scenario----------
call: 3 / sec
concurrent call: 30
total call made: 1002
failed call: 21
failure rate: 21/1002
From the log shown below, most of the error are created with message
481.
