This server is recording all calls (placed to record the audio in a ram disk), the entire CDR goes straight to MySQL by cdr_mysql.so. Each call runs some validation and AGI's have an auto dialer system that generates calls over the manager. Calls originate and terminate via SIP (no transcode). </div>
<div><br></div><div>With this structure, even being a great server, we can not spend 150 simultaneous calls. When it reaches 140, the load average goes up a lot and the calls start to get very bad audio, tear, etc.. Using the top we see that all the processing is for asterisk. In this scenario, I think there is some limitation in Asterisk, or even the manager due to the auto dialer. </div>
