ACMA amends numbering rules to accomodate VoIP services

Media release 9/2011 - 27 January

The Australian Communications and Media Authority has changed the geographic numbering rules to improve flexibility in the Numbering Plan to recognise the realities of newer services, such as voice over internet protocol (VOIP) services.

The changes come into effect on 1 February 2011.

The two targeted amendments to the Numbering Plan remove the limitations on outbound only services (including VoIP) and provide a framework governing the use of geographic numbers when used for services outside their normal area.

'The introduction and uptake of new services such as VoIP has challenged the relevance of parts of the Numbering Plan, which dated back to 1997, to meet industry and consumer needs,' said ACMA Acting Chairman, Mr. Richard Bean.

'The implementation of these amendments represents a small but important step in regulatory transition for VoIP and other converged services. It will support innovation in the new telecommunications services being offered to Australian consumers,' he said.

While VoIP services have been available in Australia for some time, these amendments give VoIP providers more certainty about how numbers can be used and what information they must provide to consumers if the geographic numbers are issued to customers out of area.

The ACMA is currently examining a range of emerging numbering issues and has already released two issues papers, most recently Customer location information and numbering data. The first paper-Numbering: Structure of Australia's telephone numbering plan, released in October last year looked at the underlying structure of the Numbering Plan.
