[asterisk-users] server performance....

[Sevana Oy]

Hi,

We have worked out another approach for load testing:

- generate using sipp certain number of test calls and that go to PBX echo 
server playing and receiving back pre-defined audio
- generate +1 test call, which also plays and receives back an audio file

Then we test the audio we received from the +1 test call using AQuA (Audio 
Quality Analyzer) and obtain a MOS score (AQuA is doing perceptual audio 
quality assessment, it's not calculating MOS as in G.107, but more likely in 
P.862, although the algorithms are absolutely different).

In this way we can always know how many calls can the PBX under test handle 
before actual call quality goes down. The whole test suit is put together 
with other testing (loop back call testing, conference bridge testing) 
capabilities into what we call Asterisk VQM. If my previous message goes 
through moderation you will be able to see screenshots as well :)

Best Regards,
