iiNet VOIP numbers will always map correctly onto the proper call zone
since the company uses the ADSL phone number to determine the CZ.
However, a not commonly recognised fact is that a metro call zone will
contain a number of exchanges - the Perth CZ for example extends from
Vic Park to the coast, and from Wanneroo to Spearwood (ish). Fremantle
is a separate call zone (technically a precinct, but unless you're
Telstra there's little difference between the two).

Location based services are a problem largely because number allocations
from smaller carriers sometimes aren't recognised, and can never be tied
back to an exchange. ACMA publish the number range / CZ mappings, but
no-one publishes the number / exchange mappings except Telstra. And
there's have sizable exceptions.
