Asterisk V1.4.11 Performance! Tested, verified and documented.

Good Folks at Transnexus who did a performance test on OpenSER a while back, recently performed an in-depth performance test on Asterisk V1.4.11 configured as a SIP B2BUA. This test was conducted on a server with two Xeon 5140, dual core, 2.33 GHz CPUs and 4 GB of RAM.

The Good news is that they found an Asterisk B2BUA on this hardware can manage 1500 simultaneous calls with no transcoding and 400 simultaneous calls with G.711 to G.729 transcoding.
So why are we limiting Asterisk Appliances to 50 Users?

A summary of the test is available
