Hello, We did small test with sipp to test Asterisk Background command capability. Our goal was 700 sim. calls on HP Proliant DL160 G5 E5405 1 x Quad Core Xeon 2Ghz 2 Gb RAM Asterisk 1.4.18.1 Centos 5.2 We reached more then 1000 when our network (100mbps) become a bottleneck. As we achieved our goal - no further testing was performed. As conclusion - we are very happy with Asterisk in this case. If somebody is interested - more details are here: http://wiki.kolmisoft.com/index.php/Asterisk_Background_performance_test Regards, Mindaugas Kezys http://www.kolmisoft.com VoIP Billing and Routing Solutions -------------- next part -------------- An HTML attachment was scrubbed...
