min-idle-cpu reserves the specified percentage of CPU idle time for other processes. This setting avoids exhausting CPU time for processes other than FreeSWITCH. If min-idle-cpu is set to 25 and FreeSWITCH processing causes the CPU idle time to drop below 25%, then FreeSWITCH will refuse to process additional calls in order to allow other processes to have sufficient CPU time available.
Used in: dialplan as channel variable
no_throttle_limits serves as override to the min-idle-cpu parameter. It may be used on a per call basis when set in your dialplan.
