<p>I do not recall if pike is enabled by default in the base config file or not, but you may be running into it blocking you.</p>
<p><br>
</p>
<p>Check to see if WITH_ANTIFLOOD is defined. If it is and you want it you will need to adjust your pike modparams. If it is enabled, and you do not needed remove the define.</p>
<p><br>
</p>
<p>If it is not enabled, it must be something else completely.</p>

<div> </div>
</div>
<div>
<div dir="ltr">Greeting list.
<div><br>
</div>
<div>I am doing the load test of Kamailio with SIPp using most basic script(kamailio.cfg) with logging level set to minimum to dispatch requests to SIPp UAS. </div>
<div><br>
</div>
<div>This is my dispatcher code snippet. </div>
<div><br>
</div>
<div>
<div> $avp(quality) = "1";</div>
<div> ds_select_dst("$avp(quality)", "4");</div>
<div> route(RELAY);</div>
</div>
<div><br>
</div>
<div>At 70 CPS calls work fine. But if I increase CPS to 80, Kamailio stops accepting calls for few seconds and comes to life after being idle for some time. </div>
<div><br>
</div>
<div>100 CPS for sip proxy is not hot cake. </div>
<div><br>
</div>
<div>Also, I see in <a href="http://www.kamailio.org/docs/openser-performance-tests/">http://www.kamailio.org/docs/openser-performance-tests/</a> tests were made with -l27 and -m7000 which looks wronged to me.<br>

192.168.2.102:5070</a> -m 200000 -r 7000 -d 1 -l 27 </span><br>
<br>
There must be something wrong in my configuration since this cps is very low. <br>
