WASHINGTON -- NeuStar, Inc. (NYSE: NSR - News), a provider of essential neutral third-party interoperability services to the global communications industry, today introduced SIP-IX, the first comprehensive suite of services designed to enable direct network-to-network peering between trading partners for voice, video and content services using Session Initiation Protocol (SIP)-based technologies such as IP multimedia (IMS) and VoIP.

Additionally, NeuStar announced a global initiative that includes exclusive relationships with top Internet Exchange Providers Equinix, Inc. (Nasdaq: EQIX - News) and TELEHOUSE. NeuStar also announced a relationship with the non-profit Amsterdam Internet Exchange (AMS-IX). These initial relationships form the beginning of a community of neutral infrastructure service providers to deliver SIP-IX.

Internet Exchange Providers offer neutral public and private IP network layer peering services where virtually all IP networks directly or indirectly interconnect, enabling the global IP network infrastructure, including what is known as the Internet. Collectively, AMS-IX, Equinix and TELEHOUSE interconnect more than 640 global IP networks, representing the significant majority of the IP network traffic for North America and Europe.

SIP-IX will build on the existing IP network-level peering foundation provided by global Internet Exchange Provider partners, and will provide a higher layer of services essential to enable network operators to exchange SIP traffic for advanced services. With SIP-IX, network operators offering SIP-based applications, including VoIP, IMS, Multimedia Instant Messaging, video calls and content, and Push-to-Talk over Cellular, will be able utilize existing IP network peering facilities to originate, terminate and share calls or sessions for mobile, fixed and broadband communications.
