Net2Phone's ADIR Technologies Launches Voxis VoIP Management Suite of Products
First Real-Time VoIP Performance - Management Software Solution for Large Service Providers

NEWARK, N.J. --Oct. 17, 2001-Net2Phone, Inc. (NASDAQ: NTOP) today announced that its majority-owned subsidiary Adir Technologies, Inc., a leading supplier of software for Voice over IP (VoIP) networks, launched the Voxis VoIP Management Suite of products. Voxis is a comprehensive, easy to use performance management solution for large VoIP service providers worldwide.

Voxis is the first VoIP performance and fault-management software solution that offers service providers the highest degree of visibility and control at the call level, in real-time. In contrast to IP network products that focus on data packets, Voxis is designed to address the specific needs of service providers who operate VoIP telecommunications networks. In addition, the Voxis Suite is compatible with Cisco 2600, 3600, 5300 and 5400 voice-enabled hardware platforms.

The Voxis VoIP Management Suite was originally developed to support the worldwide operations of VoIP market leader Net2Phone. It is thus already proven in a production environment, capable of handling tens of thousands of simultaneous calls across thousands of gateways. The Suite uses a distributed architecture that makes it easy to scale up to the requirements of the largest VoIP networks, yet requires very low bandwidth to capture large amounts of real-time data.

"This is a significant milestone for both Net2Phone and Adir Technologies as we begin to see incremental financial return on the six years of research and development Net2Phone has dedicated to the management platform," said Howie Balter, CEO of Net2Phone. "By leveraging Adir's strong strategic relationships and technological expertise, we can extend the Net2Phone standard worldwide, as well as interconnect with countless Cisco-powered networks."

Voxis provides an end-to-end, call-level view of VoIP network performance, instantly, so service providers can proactively identify the root cause of problems. This enables them to provide excellent voice quality, minimize service outages, grow subscribers and revenue per minute, and minimize investment in infrastructure and staff.

"The leading world providers in VoIP tell us that our products have contributed significantly to their success. The Voxis VoIP Management Suite is a must have for any service provider looking to offer exceptional QoS to their customers," said David Greenblatt, Chief Executive Officer of Adir. "The goal is to troubleshoot any problems before the customer realizes that something is wrong. Voxis, with its PSTN and IP testing and complete call-level view of network activity, is unparalleled in the current marketplace."

The Voxis Suite includes:

• Voxis Dashboard: True real-time call-level "console" that displays gateway, span, and call detail information, enabling service providers to quickly identify and resolve problems.
• Voxis Miner: Intelligent data reduction, analysis, alarming, and reporting that support SLA management, network troubleshooting, and fraud detection.
• Voxis Dialer: End-to-end PSTN testing and analysis that measures and reports on call completion, access, and voice quality.
• Voxis Streamer: IP "mesh testing" systematically measuring packet loss, jitter, delay, and other metrics regardless of how large and intricate the network grows.

Taken together, these components provide a comprehensive, end-to-end picture of network performance. With this information in hand, service providers can limit incremental hires of operations and customer support personnel as network complexity increases, as well as limit unnecessary expenditures on incremental hardware. They can also roll out new revenue generating enhanced services with confidence. More technical information about the Voxis Suite can be found by emailing Adir at sales@Adirtech.com.
