几种XMPP客户端实现Jingle语音聊天的总结
XMPP客户端除了最基本的发送/接收消息,显示好友列表等功能外,语音/视频聊天,文件传输等功能也很有必要. 而XMPP Jingle是实现媒体流的协议. 既然一些客户端和服务器都支持XMPP Jingle, 所以就想测试一下语音聊天的功能.
这里要测试的XMPP客户端有Psi和Spark, 要测试XMPP服务器有Openfire和Google GTalk Server (talk.google.com:5222).
我的网络环境是, 家里有2台笔记本,都通过Wifi连接到无线路由器,而无线路由器通过ADSL连接到外网. 每台笔记本都安装一个客户端, 然后想通过两个客户端来语音聊天. 其中在一个笔记本上同时安装了Openfire服务器.
下面就是我整个测试过程,步骤挺曲折的,无数次失败,好在总算摸清了规律,并且成功了一个case.
Case 1: LaptopA安装了Spark和Openfire, LaptopB安装了Spark.
接收方可以收到语音聊天邀请,但Accept后,发送方或者接收方最后会提示"Session closed due to Closed Remotely"或者"Voice chat ended: No Media Received. This may be caused by firewall configuration problems."
在网上发现很多人也遇到过这样的问题, 但至今没有答案, 而且我将firewall关闭后还是不行. 分析XMPP packets, 一切都是正常的.
