REDWOOD CITY, California, October 22 /PRNewswire/ --

- New functionality brings more speed, control and manageability to IP 
telephony routing, boosting IP telephony margins

Nominum, the leading provider of network naming and addressing solutions, 
announced today the release of Navitas 3.0, an IP-application Routing 
Directory (IPRD) that uniquely accelerates the deployment of IP telephony. 
Navitas 3.0 provides a platform that integrates legacy telephony numbering 
plans and IP routing identifiers, giving carriers an evolutionary path 
toward profitable business models using Voice over IP (VoIP). Additionally, 
the directory enables the consolidation and simplification of routing plan 
management processes, improves telecommunication margins, and optimizes 
usage of profitable and reliable routes.

Many carriers have made the decision to migrate to IP telephony. They are
challenged by declining voice revenues and face increasing competition and
industry pressures to adapt their existing business model to remain
profitable. At the same time, they need to invest and execute very carefully
as they move to IP. Cost, control and complexity are significant barriers.
Navitas 3.0 enables carriers to easily transition to an IP telephony business
model and extend telephony services to support a voice enabled Web, without
having to duplicate network functionality between legacy signaling systems --
such as Signaling System 7 (SS7) -- and IP.

"As the convergence juggernaut continues, carriers will increasingly
struggle to sustain their business model and profit margins," said Brian
Partridge, program manager in Yankee Group's Enabling Technologies Service
Provider group. "Rather than equating VoIP and VoIP peering for settlement
free services, carriers are increasingly seeking networking functions such as
IP-application Routing Directories to manage and bill telephony services on
IP as they see fit."

Navitas Answers Carriers Needs Today, Prepares Them for the Future

Navitas 3.0 serves as the foundation for next-generation networks like IP
Multimedia Subsystem (IMS) by allowing carriers to reuse existing routing
plans, and modernize the integration into next-generation networks through
automation. Through its enhanced management and reporting functionality,
Navitas 3.0 provides a higher Quality of Service (QoS) over IP by ensuring
reliable call deliveries across interconnects. The solution also helps
carriers avoid increased spending on Time Division Multiplexing (TDM) and SS7
technology, and facilitates the development of new IP-based applications.

"VoIP interconnects are growing around the globe and service providers
require scalable address resolution as well as security and control at the
interconnect borders," commented Seamus Hourihan, Vice President Marketing
and Product Management, Acme Packet. "Both Acme Packet and Nominum are
attentive to our customers' requirements for VoIP peering and we continue to
innovate and deliver features designed to build reliable, scalable and
trusted VoIP interconnects."

Navitas Delivers Advanced Features

Navitas 3.0 dynamically accesses, stores and manages telephone routes and
number mapping, while serving both legacy and converged IP switching
infrastructure with route resolution for call termination. The solution
features functionality for advanced service routing capabilities such as
voice, multi-media sessions and IP applications.

New to Navitas 3.0 are the Application Routing Module and Element
Management System. The Application Routing Module (ARM) enables Navitas 3.0
to become a switch-agnostic signaling data repository that refines telephony
and multimedia routes based on session parameters like cost, quality,
capacity and content (end user context like persona, presence, location,
etc.) The core technologies and features include:

-- Cascading query engine federates multiple sources of routing data 
    -- Support for parameter-based routing including Least Cost Routing 
       applications improves telecom margins through profitable and reliable 
       routes
    -- Framework for Service Oriented Routing (SOR) for resolution of multiple 
       routing decisions

"As the industry transitions to an all-IP world, carriers require a
robust IPRD that is switch and data source agnostic and can serve as a
control point for advanced services," said Tom Tovar, chief executive
officer, Nominum. "Navitas 3.0 provides the pivotal first step toward a
cost-effective migration from SS7 to IP. This product addresses the immediate
needs of the VoIP and VoIP peering markets as well as future network
requirements, without requiring carriers to wait for all-IP or IMS
architectures."

Navitas Element Management System (EMS) is a turn-key solution that gives
carriers a single point for administration across a network of Navitas IPRD
and ARM servers. It provides enhanced data collection and reporting and
allows for accurate Quality of Service (QoS) measurements.
