android - Checking the status of a phone call remotely

Question

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 service call phone 2 s16 "some phone number" and then sending input keyevent 5 to press the call button.

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?

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.

Answer 1

adb shell dumpsys telephony.registry | grep mCallState, will return:

• 0 indicates idle,
• 1 = ringing and
• 2 = active call
