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.
