  • Priority Local rate 13 is 6 digits
  • Priority Local rate 1300 is 10 digits (no support for the 4 digit overrun)
  • Freecall Special 1802 is 7 digits
  • Freecall 1800 is 10 digits (no support for the 4 digit overrun)
  • No mobile
  • No International dialing prefix
  • No support for brackets on areacode or priority number prefix (conscious decision)
