BT Global Services has invested $US21 million in a global, IP-based platform which will replace its current legacy TDM network across 30 countries.
Almost half the initial global rollout plan applies to the Asia-Pacific region and is part of the company's 21st Century Network (21CN) program in the region.
The company says the upgrade is in response to an average 45 percent year-on-year growth in overall voice traffic in the Asia Pacific.
BT Asia Pacific president, Allen Ma said seven nodes have already been rolled out across Asia-Pacific markets including Australia, Singapore, Hong Kong, India and Japan.
"The resulting IP voice network is a first for the Asia Pacific and supports traditional voice services as well as advanced multimedia features," he said.
"In addition, it offers a never-before- seen level of integration between applications and network services. This is of particular benefit in the CRM area where a customer's CRM application can be integrated with the network."
BT networking president, Tom Craig said a single IP platform avoids the complexities and overheads of a patch-worked networking environment.
"The investment also allows BT to easily integrate all its global networks to achieve improved cost control and customer integration to convergence," he said.
The first phase of the program has already been delivered, offering services over the new platform in 12 countries.
The new platform will be rolled out to three new countries per quarter while the legacy platform will be withdrawn in 2008.
