Leading Thai Wireless Carrier Expands Voice Portal with Intervoice Service Gateway.

True Move to Enhance Customer Experience, Lower Operational Costs with Highly Reliable Voice Self-Service System

DALLAS -- Intervoice, Inc. (Nasdaq:INTV), a world leader in converged voice and information solutions, today announced that True Move, the fastest-growing provider of mobile services in Thailand, will be enhancing its current voice solution with Intervoice Service Gateway to support its growing customer base of over five million subscribers, while lowering operational costs. With a high annual growth rate, True Move is using Intervoice's carrier-grade platforms to expand the company's existing voice portal to facilitate pre-paid mobile phone subscribers, Internet and WiFi users. This will give True Move customers an enhanced customer experience with a quick and easy-to-use self-service system.

True Move's success and voice portal expansion underscores the growing cellular phone market in the Asia-Pacific region. In today's wireless marketplace, service providers are facing declining profit margins due to increased competition. To overcome this, providers must find new and efficient ways to automate their systems and operations. They must also create and offer new value-added services to their customers. And providers must do both in a way that extends the value of their existing network assets. Service providers can now meet these objectives with Intervoice Service Gateway which combines multiple IVR functions in a single highly efficient platform.

"At True Move, everything we do is designed to support our more than five million customers and their mobile lifestyles today," said Mr. James Leander Powell, COO Mobile at True Move. "We consider our continued investment in Intervoice technology a critical step in being able to not only better service our customers with leading-edge voice self-service solutions but also in gaining a significant competitive advantage in the Asia-Pacific marketplace."

Intervoice Service Gateway is a comprehensive voice solution that enables carriers to lower operational costs by up to 25 percent. The solution leverages open standards including SIP, VXML and CCXML, enabling carriers to integrate additional revenue-generating, telco-grade applications without increasing the footprint of the system. These applications include televoting and premium-based calls such as horoscopes and sports. With a compact footprint, network operators such as True Move can conserve valuable central office space and save on training and maintenance from the convergent Intervoice messaging and voice platform.

"To remain competitive and improve profitability in today's marketplace, service providers must offer their subscribers high-value voice and speech self-service solutions," said Michael Greco, managing director, Asia Pacific, for Intervoice. "Utilizing Service Gateway from Intervoice, we are helping True Move increase customer satisfaction, retention, and loyalty in a region that is of key importance to Intervoice."
