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.
