title: How to play beep audio file during outgoing call and transmit to receiver
body: <p>We have implemented pjsua2 library for calls. We are facing some issue in playing audio during outgoing calls. We have also implemented call recording functionality which is working fine. I am not sure how to play a wav file during call which can be heard by receiver too.</p>
  
  <p>We have checked pjsua2 document which is not that up to mark. </p>
  
  <pre><code>getPlayer().createPlayer("file:///android_asset/1540Hz14s8000.wav");
  audioMedia.startTransmit(getPlayer());
  getCap_med().startTransmit(getPlayer());
  
  
    public static AudioMediaPlayer getPlayer() {
          if (player == null) {
              player = new AudioMediaPlayer();
          }
          return player;
      }
  
  public static AudioMedia getCap_med() throws Exception {
          if (cap_med == null) {
              cap_med = MyApp.ep.audDevManager().getCaptureDevMedia();
          }
          return cap_med;
      }
  </code></pre>
