[Freeswitch-users] Calls per second on FreeSWITCH

I'm trying to increase the number of calls per second that I can originate from FreeSWITCH, but I cannot seem to get more than two-per-second. (I am trying to use FS to initiate thousands of calls quickly) switch.conf.xml I beefed up the max-sessions and sessions-per-second in the switch.conf.xml file, but that did not seem to make any difference. Any thoughts? - Tina
