It is important to note that simultaneous calls depends only on hardware you are using.

2008.03.01 1575 simultaneous calls (2049 channels)

  • 2 x Quad-Core Xeon 5300 "clovertown"
  • 4 Gb RAM
  • Debian 4.0
  • 2.6.18-5-amd64 #1 SMP Tue Oct 2 20:37:02 UTC 2007 x86_64 GNU/Linux
  • Asterisk 1.4.15
  • canreinvite=no*
  • ~15% calls with transcoding (~85% calls no transcoding)
  • CPU busy 83% (17% idle)
  • Comments:
    • why channels/2 != calls?
    • because not all of them was connected
    • and when the system is loaded the channels stats update slow
    • in that day we got to almost 3500 cc
    • when you have a lot of invites, the system get very slow
    • we got to 220 setup calls per second
    • and the system was very havy
    • in that load, your app was very good, however mysql become the bottlenack
    • so i had to tweak it a little bit, but we already talked about it.
    • with your app, from the time we installed, we already did more then 30M minutes.
    • this setup can handle around 4k cc easly with no high rate cs per second

  • canreinvite=yes means that voice traffic goes from client to provider directly bypassing MOR system
