이 코드를 사용해보십시오. MediaRecorder.AudioSource.VOICE_CALL

folder = this.getFilesDir().toString();   
    String fname = "";   
    try   
    { 

     android.media.MediaRecorder mr = new MediaRecorder(); 
     mr.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL); 
     mr.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); 
     mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 

     fname = folder + "/aa"+System.currentTimeMillis()+".mp4"; 
     mr.setOutputFile(fname); 
     mr.prepare(); 
     mr.start(); 

     /////////////////////////// 

     hold here and make call then release the execution. I tested by debug and add the bread point here. 
     Thread.sleep(1000); 

     //////////////////////////// 

     mr.stop();   
     mr.reset(); 
     mr.release(); 

     MediaPlayer player = new MediaPlayer(); 

     FileInputStream fis = new FileInputStream(fname); 
     FileDescriptor fd = fis.getFD(); 
     player.setDataSource(fd); 

     player.prepare(); 
     player.start();   
    } 
    catch(Exception ee) 
    { 
     Log.d(Utils.Tag_Log, ee.toString()); 
    }
