yes, I mean that, I see some of today dbus introduces, but unfortunately, I didn't find any testing microphones and headphones signal flow function, because sometimes because both sides gets off the phone, both parties all forget according to end the call button, so, will waste a lot of words fee, if there is a software can automatically detect whether calls the subjective-microphones and headphones are constantly strong signal, flow rate, if not for the judgment is subjective state of calls, can change the light color or issue vibration to hint,,,,,,,

是的，我是这个意思,我今天看了dbus的一些介绍，但很遗憾，我没发现有检测麦克风和耳机信号流量的函数 ，因为有的时候因为双方打完电话后，双方都忘记按结束通话的按扭，这样的话，会浪费很多话费，如果有个软件 能自动检测通话是否主观的-----即麦克风和耳机都不断有较强的信号，流量，如果没有则可判断为非主观的通话状态，可以改变灯光颜色或发出震 动以提示，，，
