- 双音频按键识别 背景： 打电话拨号时，每次按键会发出不同的声音，这些声音实际上是由一些固定频率的正弦信号合成的。因为每个按键声音包含两个不同频率的正弦信号，因此也被称为“双音频”信号，简记为DTMF。这相当于是对不同键位用‘音频’进行了编码，如同计算机领域中用数字0和1对处理对象（包括键盘）进行编码。-Two-tone buttons identify Background: When you call dial, each key emits different sounds, whi

- 先说下几个要点： 1. 电话拦截这个功能大家可能都知道了，就是利用反射原理调用ITelephony的隐藏方法来实现。这个就不说了，在附件的代码里有。 2.拦截后提示忙音/空号/已关机/已停机这个功能其实是要用到MMI指令，具体如何设置呼叫转移的指定可以参考这里 http://baike.baidu.com/view/206402.html?fromTaglist。 在本文中我们会用到“遇忙转移”转移的功能。中国移动的设置方式是 **67#电话号码#，取消方式为 ##67#。这两个指令可以直接在手
