There are two different ways how to make calls with fonYou. If you are in front of a computer follow these instructions:
From your address book or call inbox chose the contact that you would like to call using your fonYou number.
Select the phone number you want to call from the different numbers stored under the contact (if more than one).
Now call your fonYou number from one of the telephone numbers that you previously registered in your user space.
fonYou automatically redirects you to the phone number you wanted to call. The person you are calling only sees your fonYou number.
If you are not in front of a computer you can make calls through fonYou’s voicemail system following these steps:

1. Call your fonYou number from one of your registered telephone numbers.
2. Introduce your PIN.
3. Chose option 2 ( “Llamar” ) and follow the instructions given there.
