SIPGO is library for writing fast SIP services in GO language. It comes with SIP stack (RFC 3261|RFC3581|RFC6026 optimized for fast parsing.

设备新增接口会同步返回SIP服务器相关配置; 通道（/channels） 通道为连接到NVR/DVR上的摄像头 或者 支持28181协议的摄像头; 通道采用注册制，通过API接口生成通道参数

gosip (pronounced "gossip") is a library that lets you make phone calls using the Go programming language. It provides a full-stack SIP/RTP implementation that's tailored towards making calls over the PSTN through services such as Flowroute. …

The objective of GoSIPs is to develop a Golang stack interface and implementation to the Session Initiation Protocol (SIP) that can be used independently or by higher level programming entities and environments.

另外我还写了个 C 语言版的 client： https://github.com/frams163com/sip_client go 貌似没有很强大的 SIP 软件，考虑到 go 可以直接调用 C library，做了个exosip封装，还在完善中。

对比了很多sip库的实现，有的与标准sip差距太大，有的实现的太复杂。osip2比较容易懂。所以这个代码参考（抄袭）的osip2 和 exosip2的相关实现。比如状态机的对应管理连函数名都没改。
