Submit one or two phone numbers to Paul (cleaner).
Make sure your fob has been programmed for the new system (as well as the old).
Callers press the floor followed by 1-8 (representing A-H) and then "Call". The system dials the first telephone number. If you answer, you can speak to the caller and press a button on the phone to let them in. If the number is busy or not answered, the second number (if there is one) will be dialled.
