Hi,

I use sipp to performance test on freeswitch. The test environment is as following,

sipp(uac 10.51.50.5 ) <->(10.51.50.4) freeswitch(10.51.51.4) <-> sipp(uas10.51.51.5 )

But when the new call rate reaches 150 new call per second, after a little while the sipp uas shows the following error. Is there something wrong with my test case?

In what environment the freeswitch will send Bye to sipp(uac and uas) ?

Thanks
-Congxin
