Laszlo Systems Tapped by Sylantro Systems for Rich Internet Portal Applications

Based on OpenLaszlo, New Portal Enables Sylantro's VoIP Phone Users and Network Administrators to Easily Manage Accounts

At SUPERCOMM 2005 CHICAGO (June 7, 2005) - Laszlo Systems, developer of the OpenLaszlo platform and provider of rich Internet applications (RIAs) and services, today announced that Campbell, Calif.-based Sylantro Systems Corporation, the leading provider of hosted PBX and IP Centrex applications and consumer broadband voice applications via the company's carrier-grade applications feature server, has selected the OpenLaszlo platform for its hosted Voice over Internet Protocol (VoIP) customer portal.

Sylantro's Senior Vice President Marketing and Operations, David Illing, commented, "Sylantro is committed to delivering the best possible user experience to our growing customer base so it's critical that users can easily manage their phone usage, account settings and related reports. We chose easy-to-use rich Internet portal applications using OpenLaszlo to further differentiate Sylantro's value through a unique next-generation Web experience. Laszlo Systems has been instrumental in delivering on that vision."

Laszlo Systems CTO and co-founder, David Temkin said, "Sylantro provides carrier-grade scalability and reliability consistent with service provider deployments that serve millions of users. This demand is consistent with the types of customers we serve by translating their complex business-critical applications into simple-to-use, elegant user experiences that deepen brand loyalty and help attract new customers."

OpenLaszlo-powered applications integrate with third-party applications and, in the case of Sylantro, enable phone users and network administrators to manage their accounts through interfaces that are role-based and presented in a single-page, highly intuitive manner. The hosted communications user portal enables those customers to manage their account, contacts, call routing and phone settings. Network administrators are able to manage users and phone lines and generate reports. By allowing self-service account management through OpenLaszlo enabled applications, Sylantro empowers users to take ownership of their options while driving down support costs, which is particularly crucial in the competitive telecommunications market.

Illing added, "Thanks to our relationship with Laszlo Systems, carrier clients have new alternatives for developing custom portals with their own 'look and feel', unique application and multilingual support to build brand awareness and foster customer loyalty. We've forged the way for carriers to emulate this same user experience under their own brands."

Sylantro Systems unveiled Sylantro Application Feature Server Release 4.0 at the SUPERCOMM 2005 Conference. For additional information about the Sylantro Feature Server, please visit Sylantro in booth # 59039, or at www.sylantro.com.
