Hi Tanyapisist,

Well although it is fairly outdated your OS is still supported by 3CX:
https://www.3cx.com/docs/manual/

Can you check your hardware specifications match up to the recommendations on the 3CX website for a the simultaneous calls of your system: https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/

Try running the following benchmarking tool on your server (Outside of working hours of course).
http://ssd.userbenchmark.com/

It'll tell you how the components on your machine are running and thus helping you identify whether this is a hardware issue or not.

Also what 3CX version are you running?

How many extensions do you have and what devices are you using for those extensions? Are you using ip phones or 3CX clients? Also is this a busy system?

Can you check the 3CX services and see what service is causing the CPU usage? Also is this a dedicated machine for the PBX?

 

[Tanyapisist]

Yes, machine for PBX

Can you try restating the management console service and let me know if that reduces the load o the CPU?

Hi, did you ever get to the bottom of this? I see the same issue with one of my installs. It is the PhoneSystem 01 SIP Server that is running around 96% for a very long time. Restarting the server drops it down to normal.

I would recommend creating a ticket regarding this with our support department so they can take a look at the logs of the system and see what is causing the issue.
