Softswitch performance

Single server performance

Performance of MOR has been tested with big traffic load and maximum capacity is around 500 concurrent calls per server if:

• SIP protocol is used
• There's no call transcoding
• GUI, IVR, Recordings and other extra services are not in use
• CPS (calls per second) is low (<5).

Multi-server performance

However, if you need >500 concurrent calls, there are two options:

• Use direct media (send just signalling through MOR). In this case MOR will be able to handle up to 4000 concurrent calls
• Use multi-server implementations. In this case there are no limits of servers you can add and each core server will handle 500 concurrent calls

Factors which determine call performance

Call capacity vary depending on the following factors:

• Hardware specifications
• Components running on same server (splitting database and GUI on different server increases performance a lot)
• GUI usage (to generate invoices, reports, etc)
• 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)

To get an idea how many concurrent calls MOR can handle, please check results of stress tests.
