According to the study, common challenges involved in rolling out integrated networks include difficulties in managing the network (cited by 54%), security and risk management concerns (21%) and difficulties in measuring ROI on the project (15%).

Other internal CA research suggested that a failure to measure existing voice and network traffic prior to rolling out a new single IP-based network was a common cause of failure, CA enterprise systems management business unit director Simon Barnier told a breakfast briefing in Sydney this morning.

While the transition to IP telephony may appear irreversible, businesses are taking their time in making the shift. Since 2005, IP telephony equipment has outsold traditional PABX equipment, IDC senior analyst David Cannon told the briefing.

However, of the six million currently active business telephone lines in Australia, only 2 million are currently running on an IP network. "Come this time next year, though, it's going to be a 50:50 split," Cannon said.
