The app calls unknown numbers

You may have noticed that when you call, the number displayed on the screen is different from the one you dialed. This number is actually an Onoff server which allows communication to be established to the number you wish to reach.

Don't worry, it doesn't change your call, and your correspondent will only see your Onoff Business number!

Be careful, however, if you use the application from a country other than your Onoff Business number, your operator may bill you for international calls.
