Sep 18, 2000

ATLANTA, Georgia - September 18, 2000 - TransNexus, Inc., the leading provider of standards-based IP telephony clearinghouse solutions and one of the original co-developers of the Open Settlement Protocol (OSP), today announced the commercial release of its OSP NexusTM Server - Carrier Edition. The OSP NexusTM Server - Carrier Edition, a robust and highly reliable Open Settlement Protocol server, enables routing, authorization and usage information reporting for IP communications among multi-vendor, multi-protocol networks, and offers clearinghouse service providers a carrier-grade alternative to proprietary clearinghouse solutions. OSP, defined within the European Telecommunications Standards Institute, is a future proof standard designed to interoperate with H.323 and SIP networks and future IP network applications and protocols. OSP enables the real time exchange of authorization, accounting and usage information between service provider domains for IP telephony.

"OSP is an important factor in our global clearinghouse strategy. An OSP platform, such as the OSP NexusTM Server, will enable our clearinghouse operation to provision and manage commercial interconnection among any combination of service providers using different vendors and VoIP protocols," stated John Mulligan, Chief Technology Officer, Concert Global Clearinghouse.

The OSP NexusTM Server - Carrier Edition, operated as a stand-alone server, or in parallel with multiple servers for high availability, offers convenient, centralized, in-house administration of call routing information and flexible call routing capabilities based on source IP telephony device, destination telephone number and load balancing criteria. The OSP NexusTM Server - Carrier Edition employs the strongest possible security available for call authorization among inter-network IP telephony devices. Authorization tokens, using the latest, public key cryptography technology, protect IP telephony devices from fraudulent or unauthorized access.

Administered through a standard web browser or via a simple text configuration file, the OSP NexusTM Server - Carrier Edition enables devices supporting OSP to query the server for call routing and authorization information and to report inter-network call detail records to a centralized location. The OSP NexusTM Server - Carrier Edition integrates easily with external billing/provisioning systems, for the export of call detail records for Voice over IP settlement and billing.

"Cisco's Open Packet Telephony strategy relies on international standards, such as OSP, and on key partners, such as TransNexus," said Alistair Woodman, director of marketing for Cisco's Packet Telephony Division. "The introduction of a multi-vendor, carrier-grade OSP server from TransNexus will make it much easier for VoIP service providers to interconnect and will further accelerate the growth of the packet telephony industry."

"As an industry leader in VoIP, Lucent views protocols such as OSP and standards-based Voice over IP clearinghouse applications, such as those from TransNexus, as fundamental to the success of VoIP. Standards-based products like the OSP NexusTM Server - Carrier Edition eliminate a major commercial barrier to the widespread adoption of voice over IP technology,'" stated Josh Bottum, director of product management, Lucent Technologies.
