Flex stands for flexibility

If you're in an Optus coverage area, then ISDN Flex provides unprecedented flexibility to add lines when you need them. Get a new staff member, get a new line. One not 10. And with a new market shaking line rental, it really does become the ideal ISDN solution.




100 Number Range



100 Number Indial Range

Having one line per staff member would get a bit expensive, after all, not everyone is on the phone at the same time. But you still want everyone to have their own number, so people can reach them directly. Renting a 100 number range gives you that flexibility and more.
