private static String mFileName = null;
//private RecordButton mRecordButton = null;
private MediaRecorder mRecorder = null;
//private PlayButton   mPlayButton = null;
private MediaPlayer   mPlayer = null;

private void startPlaying() {
    mPlayer = new MediaPlayer();
    try {
        mPlayer.setDataSource(mFileName);
        mPlayer.prepare();
        mPlayer.start();
    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }
}

private void stopPlaying() {
    mPlayer.release();
    mPlayer = null;
}

private void startRecording() {
    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setOutputFile(mFileName);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);


    try {
        mRecorder.prepare();
    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }

    mRecorder.start();
}

private void stopRecording() {
    mRecorder.stop();
    mRecorder.release();
    mRecorder = null;
}

public PhoneCallRecorderActivity() {
    super("PhoneCallRecorderActivity");
    mFileName = Environment.getExternalStorageDirectory().getAbsolutePath();
    mFileName += "/audiorecordtest.3gp";
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}

@Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
Log.e(LOG_TAG, "Recording Started");
startRecording();

If you are looking to record the actual call itself (local voice and remote voice), that is not possible in Android, as the call audio information is handled outside of Android itself.
