本系统将SIP协议、STUN、RTP/RTCP协议等结合到一起,应用界面简洁清楚、使用方便。软件开启,只要输入本地用户名和远端UA用户名,或者SIP服务器名称,点击CALL按钮就可以直接和网络上的SIP的UA端进行语音通话,或者访问特定的SIP音乐服务器,收听音乐。为后续实现基于SIP协议的视频会议研究奠定了良好的基础。通过本实验得到结...

These sessions are managed by SIP dialogs, which represent a SIP relationship between a pair of user agents. Because dialogs are between pairs of user agents,...
需要注意的地方是AbstractList中的一个属性modCount。这个属性主要由集合的迭代器来使用,对于List来说,可以调用iterator()和listIterator()等方法来生成一个迭代器,这个迭代器在生成时会将List的modCount保存起来(迭代器实现为List的内部类),在迭代过程中会去检查当前list的modCount是否发生了变化(和自己保存的进行比较...
