[Freeswitch-users] mod_callCenter scalability

[Varsha Agarwal]

Thanks a lot for your feedback. That helps a lot. We are going to use this FreeSwitch instance merely for call queueing and routing. We have a main PBX that is going to handle all the incoming calls, phones are going to be registered to this PBX, it is going to handle Voicemail, IVR etc. Calls just come to Freeswitch to place in the queue and get routed to an available agent. This is should pretty light weight right?

We are going to setup load testing environment, just wanted to get a starting point from someone's experience.

I have a scenario running more than 150 queues, and 100 agents simultaneously (300+ agents in total). We process more than 10k calls per day between 0600am and 1800pm, sometimes we have more than 150 members waiting in the queue plus 90+ callers talking to agents. 

The server has a Xeon(R) CPU E5-2603 (4 cores 4 threads 1.8Ghz) 8GB RAM, two 500GB 7200 SATA disks. We’re also running our application stack for reporting and call control. We rarely stay above 50% of CPU, the backend database is mariadb through odbc (we’re migrating to postgresql due to better locking and other reasons...).

As others said, it’ll be also dependant to your hardware and environment, do your load testing (sipp or switchy) and see where is your bottleneck.

Hope this helps!
