1. Dial 0906 40 70 122 (Remember that you need
     the landline or mobile number of the person you
     want to wind up).

 2. Follow the menu options and enter the number of
     the crank call you want to play (see selection
     and corresponding numbers above).

 3. Then enter the phone number of the person you'd
     like to wind up and the system will call them.

 4. When the call connects, the victim will believe
     they are talking to a real person whilst the
     joke unfolds.

 5. You stay on the line and listen in on the crank
     call; don't worry though, they won't hear a
     sound!

 6. If your victim hangs up, stay on the line and the
     system will call them back, continuing the
     crank call with "please don't hang up again, it's
     very rude you know!".

 7. The crank call will automatically end when you
     hang up.

 8. Mission Complete!!!
