Cable & Wireless Optus Limited has notified the Australian Competition and Consumer Commission of an access dispute under section 462 of the Telecommunications Act 1997.

The dispute relates to Telstra's proposed solution to the routing of Telstra calls to ported numbers.

Accordingly, the ACCC will commence an arbitration hearing.

Given that the legislation contemplates that arbitrations be conducted in private, the ACCC will not be making any public comment at this stage.
