title: How to send VoIP calling between two android devices on Local WiFi?
body: <p>There are many questions that provide answer for streaming audio over WiFi, but I need to identify the device and send the stream only to the device which is called.</p>
  
  <p>I'm a beginner and I want to know how to get the status of the device, that is whether it is on the network or whether it is already on a call or not and how to get notification that a call is being received</p>
