Infrastructure ENUM implementation in Australia

VoIP is becoming the dominant approach for telephony and its growth will continue with the upcoming introduction of 4G mobile wireless and fibre to the home networks. With the growing demand for VoIP and increased VoIP traffic, it is important to implement a system that provides interoperability between the existing telephony numbering system and the IP network device addresses. Infrastructure ENUM is one approach that may be used as it paves the path for Service Providers to leverage the use of DNS and globally used E164 numbers to simplify the way we communicate. This paper examines the Infrastructure ENUM implementation in Australia.
