CPU Loading

Recommended Posts

I was told that PBXNSIP will not allow any additional calls once the CPU reaches 75% of its capacity.


I am not speaking of the Maximum Number of Calls: in the Performance area.


Does anyone know more about this?

That's my understanding too.

Its the Media CPU Usage: graph on the Status > General screen. Note the blue line on the graph at 75%.


Yea, it is a kind of self-protection mechanism. The 75 % is a setting and can be changed if neccessary. The closer you get to the 100 %, the more jitter you get. IMHO 75 is a reasonable value.
