title: I am looking for a way to play an audio message to recipient of a phone call as soon as he/she receives the call
body: <p>I am looking for a way to play an audio message to recipient of a phone call as soon as he/she receives the call. I want to push my audio when someone receives the call and then I start conversation. Example:- When some organization calls they start with a greetings audio message first then start the actual conversation.</p>
  
  <p>I have tried searching a lot but all the questions related to this on Stackoverflow are bit old and they mention that this is not possible. Is it still the case? </p>
  
  <p>Could someone please guide how one could achieve this in android?</p>
