Hi<br><br>How do you configure dispatcher to send OPTIONS ping to load-balanced proxies ?<br><br>I&#39;m using kamailio 1.4.2 with this of configuration:<br><br>[...]<br>modparam(&quot;dispatcher&quot;, &quot;ds_ping_method&quot;, &quot;OPTIONS&quot;)<br>
modparam(&quot;dispatcher&quot;, &quot;ds_ping_interval&quot;, 5)<br>modparam(&quot;dispatcher&quot;, &quot;ds_ping_from&quot;, &quot;<a href="mailto:sip%3Afend1@10.132.184.33">sip:fend1@10.132.184.33</a>&quot;)<br>modparam(&quot;dispatcher&quot;, &quot;ds_probing_threshhold&quot;, 3)<br>
[...]<br><br>The load-balancing works properly : I see the traffic being sent to my proxies. But I don&#39;t see any SIP OPTIONS packets. <br><br>I&#39;ve read in module doc &quot;This method is only available, if compiled with the probing of failed gateways enabled. 		
 		&quot; but I can&#39;t find how to activate this on compilation time, so I&#39;m not sure if I have this feature or not enable.<br><br>Regards,<br>Pascal<br><br><br>
