私はTwisted拡張機能で遊んでいて、チャットルームのようなシステムでだまされてきました。しかし、私はそれを拡張したいと思います。現在のところ、ユーザー名ectを使用したマルチクライアントチャットのみをサポートしています。しかし、私はpyAudio拡張機能を使用して一種のVoIPアプリケーションを構築してみたいと思います。クライアントにはclientFactoryと単純なechoプロトコルがあり、サーバーにはserverFactoryとプロトコルがあります。しかし、これをどのように構築するかは完全にはわかりません。このようなことをするための最良の方法は何でしょうか?
client.pyが必要な場合に役立つコード:

sizer.Add(self.text, 5, wx.EXPAND)
sizer.Add(self.ctrl, 0, wx.EXPAND)
