STD Leading Digit
If the 1st digit of the phone number is this number it is assumed to be national call rather
than a local call. The phone number will therefore include the area code to be dialled. Default
is ‘0’.
Area Code
The local area code. Don’t include the STD digit. For example, state of Victoria (in Australia)
has an area code of ‘3’, where locally it would be ‘03’
Local Area Code
The national area code of the region the terminal is installed.
IDD Prefix 1 & IDD Prefix 2
If either of these digits is dialled at the start of the phone number assume the number being
called is international rather than national or local. The number will therefore include the
country and area codes. Typical settings could be ‘0011’ or ‘0018’ for Australia, or ‘011’ for
USA.
Info Leading Digit
If the 1st digit of the phone number is this digit, it is assumed to be a call to a local
information service (e.g. Time, Weather). Information numbers ignore ‘Minimum Digits’ above
but have to be at least 5 digits. Area codes are not used for information numbers.
