SIP调试之SIPP测试工具-编程知识

SIPP是针对SIP协议的一个性能测试的命令行工具，可以动态显示测试的统计信息（如呼叫速率、延时、消息统计等）。用户可以通过XML场景配置文件，自定义模拟各种UAC/UAS测试场景的信令交互流程，可以被用来测试IP话机、SIP代理、SIP PBX等SIP设备。

一、参考资料

官方网站：https://sipp.sourceforge.net/
参考文档：https://sipp.sourceforge.net/doc/reference.pdf

二、安装

linux平台：

sudo apt install sip-tester

注：也可以下载源码编译安装

三、使用

3.1 查看用法

# sipp -h


Usage:sipp remote_host[:remote_port] [options]Example:Run SIPp with embedded server (uas) scenario:./sipp -sn uasOn the same host, run SIPp with embedded client (uac) scenario:./sipp -sn uac 127.0.0.1Available options:*** Scenario file options:-sd  : Dumps a default scenario (embedded in the SIPp executable)-sf  : Loads an alternate XML scenario file.  To learn more about XML scenariosyntax, use the -sd option to dump embedded scenarios.They contain all the necessary help.

3.2 常用参数说明

-v

作用：显示版本信息

-bg

作用：后台模式运行

-sd

作用：输出SIPP内嵌的默认场景

sipp -sd <uac/uas/uac_pcap>

部分参数说明：

uac: uac场景
uas: uas场景
uac_pcap: uac带媒体场景

将场景内容重定向到文件

sipp -sd uas > uas.xml

-sf

作用：加载指定的场景文件

sipp -sf uas.xml

-sn <uac/uas>

作用：使用默认的内置场景文件

# sipp -sn uas

# sipp -sn uac

-t <u1/un/t1/tn>

作用：设置传输方式
部分参数说明：

  u1: 使用一个UDPun: 一个呼叫用一个UDPt1: 使用一个TCPtn: 一个呼叫使用一个TCP

-i

作用：设置本地的IP地址，如contact,via,from

sip -i 192.168.1.100

-p

作用：设置本地的端口

sip -p 5060

-bind_local

作用：绑定本地IP地址

-ci

作用：本地控制IP

-cp

作用：本地控制PORT

3.3 场景文件

可以从在线参考文档（https://sipp.sourceforge.net/doc/reference.pdf) 中的链接获取一些内置的测试场景的xml模板，手动改变其中的一些参数或流程形成目标场景文件。
