1.Testing Platform

CPU	Main frequency	Burst	Cores	RAM	Hard Disk	Operating System	Asterisk Version
N4120	1.10GHz	2.6	4C4T	8G	MSATA 32G	Centos7.4	13.15.0
N2930	1.83GHz	2.16	4C4T	8G	MSATA 32G	Centos7.4	13.15.0

 

Related instructions:

1、Equipment matching：Intel N4120 motherboard docking test machine through sip relay

2、Test Data：Test different encodings, the maximum number of concurrent sip calls when the voice is normal

3、Call rate：Each call is 1min, internal calls are delayed for 10s, and the maximum number of initiating and stopping calls per second is set to 30

4、Asteirsk uses source code to compile, g723, g729 encoding modules use core2-sse4 64-bit so files

5、Modified the modules.conf file during the test, using chan_sip instead of pjsip

Call flow:

sip relay

ssip –→Server A ( N4120) ————————>Server B（playback demo-instruct）

2.Test method

Prepare a test server B with Asterisk, SSIP initiates a call to the A (N4120) motherboard, Transfer to Server B via SIP relay for playback. Before each test, make the cpu work at full speed.
