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 =============================================================================================================== [czhao@congxin trunk]$ sudo sipp -sn uac -i 10.51.50.5 10.51.50.4 -trace_err -d 100000 -r 200 Resolving remote host '10.51.50.4'...
