exosip

大家好,又见面了,我是全栈君,祝每个程序员都可以多学几门语言。

exosip针对UA是对osip进行扩展,oSIP不提供不论什么高速产生请求消息和响应消息的方法,全部请求消息和响应消息的形成必须调用一组sip message api来手动组装完毕,所以作者在osip上基础上开发了exosip,用exosip开发软电话非常方便,仅需几个API就能够完毕.exosip中附带一个样例:josua,只是josua相对复杂了点,以下给出一个最简单的样例供大家參考,由于样例实在太简单所以没有给出凝视,用到exosip的API的參数请參看exosip源码,看懂这个样例再研究josua就非常easy了.我使用的是osip 2.0.9+exosip 0.77.
