Performance of Asterisk Telephony System on Linux [duplicate]

  • 772

I needed some idea on the max concurrent calls a standard Asterisk Telephony System can handle on a 64 bit Linux server of 4GB RAM, 4 CPU cores and 10K RPM RAID0 HDD? Most of my calls will be reads.

Any pointers in this regard will be very helpful.

    That server will be a killer for Asterisk, you can expect over 5k+ concurrent calls without degradation, although on this scenario if you use some advanced codec (G729 for example) the CPU will be your limit.

    Have a look at this very good document about Asterisk dimensioning, lots of very useful info there http://www.voip-info.org/wiki/view/Asterisk+dimensioning

    Also Transnexus have a very good paper on CPU vs memory performance for concurrent calls http://www.transnexus.com/White%20Papers/asterisk_V1-4-11_performance.htm

  2. We are having a same setup,but with 6GB of RAM. Which is connected to a PRI line. The box is handling almost 4000 call per day including human attending and IVR
