105  Routing arrangements

 (1) A carriage service provider or carrier must not prevent, by its action or inaction in routing calls to or from a ported number, the provision of an equivalent service in relation to the number.

 (2) If a carriage service provider or carrier has routing responsibility in relation to a call to a portable number, the carriage service provider or carrier must enable call completion to the number by:

 (a) routing the call appropriately; or

 (b) ensuring correct routing of the calls to the appropriate carriage service provider or carrier for calls to the number.

 (3) The originating access carriage service provider has routing responsibility in relation to a call to a portable number except to the extent that one of subsections (4) to (6) applies.

 (4) If the call originated outside Australia, the first carriage service provider or carrier in Australia receiving the call has routing responsibility.

 (5) If the call involves number translation from the dialled number to the appropriate network address to enable correct routing (for example, in connection with the supply of a freephone or local rate service), the carriage service provider or carrier providing the translation service has routing responsibility from the point at which the translation is applied.

 (6) If the call is being diverted from one number to another, the carriage service provider or carrier providing the diversion service has routing responsibility from the point at which the diversion begins.
