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



2008.02.18 906 simultaneous calls (1801 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 58% (42% idle)

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



How can I increase the number of simultaneous calls?

Easiest way to increase the number of simultaneous calls is to connect an additional Asterisk server to your current MOR server.

Other implementations which can help you to increase the number of simultaneous calls can be found here.
