Related notes:
1. equipment with: Celeron N2930 motherboard through sip trunk docking test machine
2. Test data: test different codes, the maximum number of concurrent sip calls in the case of normal voice
3. Call rate: 1min per call round, 10s internal call delay, maximum number of initiated and stopped calls per second set to 30
4. Asteirsk using source code compilation, g723, g729 coding module using core2-sse4 64-bit so file
5. The performance screenshot is the output of WinSIP call hitting full moment using top command.
Calling process:
sip relay
Winsip --> Server A (Celeron N2930) ------------------>Server B(playback demo-instruct)
2.Test method
Prepare a test server B with Asterisk, WinSIP initiates a call to A (Celeron N2930) motherboard, which is relayed to Server B for playback via SIP trunk, and make the CPU in full speed working state before each test.
Set /sys/module/pcie_aspm/parameters/policy to performance, and use cpupower -c all frequency-set -g performance to make the CPU in full speed working mode.
CPU operating frequency:
cpupower -call frequency-info |grep "current CPU frequency"

4.Notes
1.In the test, the number of concurrent calls is gradually increased until the voice stutters after the call is full to determine the critical number of concurrent calls.
2.In the test to monitor the human ear to judge the sound quality, there are subjective differences, call the full softphone and then call all the way to listen to the voice, the voice is clear and no lagging phenomenon as the standard;.
3.Test process BIOS inside the power limit option has been removed, the test cpu in full speed work state.
