sipp模拟电信运营商VoIP终端测试(SIP协议调试)

2023-06-25,,

三大运营商和其他众多通信业务厂商都可能有SIP服务器，用来支持语音对讲，多媒体调度等功能，他们的平台可能不是标准的SIP协议会话。

为了应对没完没了的对接各个厂商的平台，这里再整理了一套协议脚本，毕竟全都是没有意义的无用功，标准化的SIP会话就是最好的。

感谢西安的枫林晨曦，帮忙抓包，整理了这套脚本。

1、先熟悉一下SIP的各种请求方法

INVITE，ACK，BYE，CANCEL，OPTIONS，REGISTER，PRACK，SUBSCRIBE，NOTIFY，PUBLISH，INFO，REFER，MESSAGE，UPDATE

SIP request methods

https://en.wikipedia.org/wiki/List_of_SIP_request_methods

2、调试协议，少不了要抓包分析数据，手机app抓包，最简单，最靠谱的就是在电脑上装个wifi热点，让手机连上这个热点，在电脑上抓取这个wifi网卡的数据。

有的电脑网卡能模拟wifi AP，如果不支持，就买个wifi网卡吧

Android抓包方法(三)之Win7笔记本Wifi热点+WireShark工具

3、各请求流程的协议脚本

不一定能直接用，一般都需要调整，因为每家都可能有差异，按照厂商给的协议文档，或者抓包信息来调整。

虽然抓包就什么都有了，但是我这里还是把运营商的信息屏蔽了，毕竟签了保密协议，免得被找茬。

不熟悉协议可以参考https://github.com/saghul/sipp-scenarios
