Yes, one can now carry a number from the old POTS system to the NBN or between NBN VoIP providers.

How it all works in the case of the NBN is interesting.  My understanding is that the big POTS providers (Telstra, Optus, others?) still "own" their long-standing blocks of allocated numbers, but each number now has an associated link to the current VoIP provider for that number.

So if customer 'A' rings 'B' then A's VoIP provider will first look up the owner of B's number ('X') in an allocated-numbers database, then access 'X' to discover B's VoIP provider.  A's VoIP call can be routed over the internet.

Of course the afore-mentioned big providers charge for their stewardship of the telephone numbers.
