WIS TELECOM demonstrates excellence in the international voice market and has extensive voice interconnection direct reach, while SAP shares experience in the rollout of IPX voice services in the Asia-Pacific region. "Today's announcement from Mobile World Congress is befitting with this year's event theme of exploring the new mobile horizon, as our agreement with WIS TELECOM changes the game for operators," said John Sims, president, SAP Mobile Services. "Direct IPX routing of voice calls to remote regions brings demonstrable improvement of quality and cost transparency. With the roll-out of LTE networks and the launch of voice over LTE, moving to IPX is no longer a choice but a necessity." IPX enables mobile operators to deliver operational efficiencies, cost savings and improves service quality to end users. They can do so by combining interconnects across various platforms, such as voice, data roaming, LTE roaming and diameter hub, roaming signalling and messaging. As a result of this agreement, WIS TELECOM and SAP plan to create a leading IPX voice proposition that supports end-to-end quality to meet growing demand across the globe. Compared to traditional IP-based voice services, this improvement in quality will be particularly noticeable on voice calls between dispersed geographic regions.
