** 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 easily, with no high rate cs per second

==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 [[Implementations | here]].

The system performance in ideal conditions (no extensive GUI usage and no transcoding):

  • MOR single-server solution - up to 500 concurrent calls, up to 50 CPS (most of the time it's closer to 20).
  • MOR multi-server solution - up to 2000 concurrent calls, up to 100 CPS
  • M4 single-server solution - up to 500 concurrent calls, up to 100 CPS
  • M4 multi-server solution- up to 10 000 concurrent calls, up to 1000 CPS.


Factors that influence softswitch performance

  • Hardware specifications (CPU, RAM, HDD type - 5400/7200 rpm, SSD, SAS, Raid, NIC etc.)
  • Network (routers/switches)
  • Providers (connectivity, quality, PDD)
  • CPS (if you accept a lot of short calls at the same time (so called dialer or call center traffic), softswitch performance decreases)
  • Structure of call (signalling only or signalling with media)
  • Processes, running on the same time (if you generate invoices, statistics or run other processes, softswitch performance decreases)
  • Additional functionality usage (if you record calls, use different IVR structures, softswitch performance decreases)
  • Codec and protocol used
  • Protocol and codec conversion (in case of transcoding performance decreases two times)
  • Calls length (if you accept a lot of short calls at the same time (so called dialer or call center traffic), softswitch performance decreases)
  • DB and GUI on same server or on the separate (if you separate DB and GUI, you can increase performance)
  • SIP balancer present or not (if you use SIP balancer in front of the servers, you can increase performance)
  • Business model (Calling Card, Callback and Call Center calls decreases softswitch performance)
  • etc

Screenshots from real use cases

In all of the below examples, companies were using recommended hardware.

MOR, single server solution, Wholesale Transit business

Implementation: single server with 24 cores, GUI is not used almost at all.

Results: up to 500 concurrent calls, up to 1500 call attempts per minute.

MOR, 4-servers solution, Wholesale Transit business

Implementation: SIP balancer, 3 Asterisk (MOR) servers and DB/GUI server.

Results: 1200 concurrent calls, 1500 call attempts per minute.
