title: Checking the status of a phone call remotely
body: <p>I want to check after starting a phone call what the status of the call is via a connected PC, if possible with the ADB.
  I'm starting a call by entering a phone number with the adb command <code>service call phone 2 s16 "some phone number"</code> and then sending <code>input keyevent 5</code> to press the call button.</p>
  
  <p>Now I'm struggeling to find a way to determine the status of the call. I need to know if the the number getting called is currently busy, if the call got cancelled or if the call was successfull/that I have an open voice connection to the called number.
  Is there any way of monitoring that?</p>
  
  <p>The phone model really doesn't matter nor the android service/app I use to call the number nor the android version. The phone will be/is rooted. I will use whatever works.</p>
