Hi Daniel, Thank you very much. I will study it further. -- Best Regards, Shengy 在 2017-05-31 00:40:57，"Daniel-Constantin Mierla" &lt;miconda(a)gmail.com&gt; 写道： children parameter is to specify the number of workers per udp socket (or other sockets, a matter of different parameters). It is normal to have more than its value, because kamailio creates also timer processes, etc. You can do 'kamctl ps' to see the list of processes and a short description of their purpose.
