while incoming call to open system app phone dialer

Question

I am setting the phone app as my default app and also getting the call inside the onCallAdded() method. but while incoming the call, should open android phone dialer, not my default dialer, like truecaller or easycallbalcklist

Service class

 public class TestConnectionService extends InCallService {
@Override
public void onCallAdded(Call call) {
    super.onCallAdded(call);
    Log.d("callservice","call came");
    }
}

MainActivity class

 public class MainActivity extends AppCompatActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    Intent intent = new Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER);
    intent.putExtra(TelecomManager.EXTRA_CHANGE_DEFAULT_DIALER_PACKAGE_NAME, getPackageName());
    startActivity(intent);
    }
}

mainfest.xml

<service
        android:name=".service.TestConnectionService"
        android:permission="android.permission.BIND_INCALL_SERVICE">
        <meta-data
            android:name="android.telecom.IN_CALL_SERVICE_UI"
            android:value="true" />

        <intent-filter>
            <action android:name="android.telecom.InCallService" />
