The number of simultaneous calls is limited only by the capabilities of your machine.


It is important to note that simultaneous calls depend on the hardware you are using.

2009.02.10 231 sim. calls alaw-g729 reencoding

2009.02.10 645 sim. calls SIP pass-through

2009.02.10 597 sim. calls SIP -> H323

2009.02.07 550 sim. calls H323 pass-through


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 were 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 gets very slow
    • we got to 220 setup calls per second
    • and the system was very heavy
    • in that load, your app was very good, however mysql become the bottleneck
    • 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
