送给sip学习者sip实例.docx

1、送给sip学习者sip实例网站上关于基于sip的java编程实例实在是太少了，这个严重影响了sip的传播和发展，所以我上传了这个小实验，让大家参考下。在做实验前，我们需要一些东西：我的环境：XPEclipse需要包：这个需要在网上自己找，或者hi我，我也可以给你们哈。-XX账号：时光可见好了，现在看程序了哈，主要是三个文件。MessageProcessor.java :public interface MessageProcessor public void processMessage(String sender, String message); public void processEr
