The application can also send a personalized text message (SMS)that will be sent at the time the incoming call is barred.
Trick: In order to bar a number in local format, insert it in your Contacts. The application will convert from local format (0620166849) to international format number (+33620166849).
After a complete stop of your Android telephone, the Autostart on Boot parameter must have been previously selected for the choosen numbers to be barred. If not you must restart manually the application.
