"[There is] a lot of the functionality that comes with [Microsoft Lync] around call queuing and call waiting and IVRs [interactive voice response]," he said. "A lot for that functionality that comes with that platform allows you to deliver call menus and we need that as part of the business."

While the initial rollout will initially only affect 500 Jetstar employees, Tame is looking to deploy it across the Jetstar network in Australia and overseas.

"With a view that we've proven this thing, we can now start to deploy it across our networks," he said. "It's proven itself as running a corporate telephony and has moved into the corporate areas."

"My executives can answer their desk phone while their at home or plug in their PC at an airport in Singapore and answer their phone in Melbourne.
