A virtual client/server solution will replace the complex inter-PBX/LAN/WAN networking currently in use, which will reduce communications costs.

Data center and disaster recovery benefits will be provided via centralization of applications and servers for voice. The Melbourne site will be configured for local survival processing as part of the company's business continuity plans.

Macquarie Telecom will provide high speed bandwidth with its metro access network while also delivering in-bound, out-bound, national and international voice calls, together with mobile services and its online fleet management tool FleetView.

Creswell said the VOIP network will reduce both communications costs, by replacing voice with data, and administration costs, by consolidating up to 10 separate bills into one.

"The minimal infrastructure, reduced points of failure, single central point of administration and cheaper cost of data compared to using standard lines will help us realize cost savings quickly," he said. "Now we enjoy a single bill and a single point of control for voice, mobile and data - this will bring about massive savings from an administrative point of view."
