                1、在CallNotifier.java (packages\apps\Phone\src\com\android\phone)中定義一個成員變數private Call.State mLastCallState = Call.State.IDLE;
2、在函式onPhoneStateChanged的開始新增程式碼
Call.State ringCallState = mCM.getFirstActiveRingingCall().getState();
Call.State fgCallState = mCM.getActiveFgCallState();
if ((mLastCallState.isRinging() && ringCallState == Call.State.IDLE) || //MT
   (mLastCallState.isDialing() && fgCallState == Call.State.ACTIVE)) //MO
{
// 進入這裡意味著電話已經接通，sergeycao一些操作
}
mLastCallState = ringCallState.isRinging()  ringCallState:fgCallState;
