[Kamailio-Users] openSER with 200 cps

[Ali Soltani]

Hi,

I am not getting any error message in the openSER log file. No database lookups or any intensive operations. OpenSER is simply relay the traffic. Machine load is only few %, more than 90% idle.
I have tried 0, 200 msec, 500 msec pause time between 180 and 200. The problem still exists. 

I also tried to dump the openSER request / responses to the log file to check the message sequence. However, the log statement in the onreply_route[1] will dump the responses received by openSER from callee, . How can I dump the responses that openSER proxy back to caller (after modifying via field) ?

route
{
   t_on_reply("1");
   ...
}

route[1]
{
   xlog("L_INFO","\n\n$Cbg[  Method $rm from $si  ]$Cxx\n$mb$Cbg[  End of Request  ]$Cxx\n");
   if (!t_relay())
   {
      xlog("replay error");
      sl_reply_error();
   };
   exit;
}

onreply_route[1]
{
   xlog("L_INFO","\n\n$Cbg[  Method $rm from $si  ]$Cxx\n$mb$Cbg[  End of Request  ]$Cxx\n");
}

Also, from the sipp script, after how much time the 200ok is sent
after the 180 was sent?
Do you let any ring time at all in your script?
