Performance of MOR has been [[Performance tests | tested with big traffic load]] and maximum capacity is around 500 concurrent calls per server if:
* MOR single-server solution - up to 500 concurrent calls, up to 50 CPS (most of the time it's closer to 20).
* MOR [[Implementations | multi-server solution]] - up to 2000 concurrent calls, up to 100 CPS (most of the time it's closer to 60).


* SIP protocol is used
* M4 single-server solution - up to 500 concurrent calls, up to 100 CPS
* There's no call transcoding
* M4 [[M4_System_Architecture | multi-server solution]]- up to 10 000 concurrent calls, up to 1000 CPS.
* GUI, IVR, Recordings and other extra services are not in use
* CPS (calls per second) is low (<5).

However, if you need >500 concurrent calls, there are two options:
* [[Recommended_hardware_for_MOR_server | 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

* Use direct media (send just signalling through MOR). In this case MOR will be able to handle up to 4000 concurrent calls

* Use [[Implementations | multi-server implementations]]. In this case there are no limits of servers you can add and each core server will handle 500 concurrent calls

Call capacity vary depending on the following factors:

* Additional functionality usage (recordings, IVRs, transcoding, etc)
* Calls length (big capacity of short calls (e.g. Call Center traffic) take much more system resources comparing with long calls)

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 (most of the time it's closer to 60).
  • 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.
