If your Siemens Telephone shows 'Not possible', 'Incorrect input', or 'Nothing stored', it indicates a problem such as an unavailable speed dial number, incorrectly entered appointment, blocked entry, unfulfilled prerequisite, or an incomplete number. You should correct your input, select a permitted option, or enter the phone number in full.
