Sipura Technology and BridgePort Networks Partner to Bring MobileVoIP to Homes and Offices

Companies to Expand Market for SIP Based Mobility Applications and Infrastructure

Sipura Technology, a leader in SIP based VoIP telephony endpoint equipment, and BridgePort Networks, a leader in MobileVoIP convergence, announced today that the companies will collaborate to enable MobileVoIP services over Sipura's SPA analog telephone adapters (ATAs) and VoIP phones. The companies will work together to ensure compatibility of Sipura's product line with BridgePort Networks' NomadicONE(TM) Network Convergence Gateway (NCG). As a result, users will be able to send and receive calls using a single mobile or fixed line phone number either through a Sipura ATA or from a Sipura IP phone or a multimode cellular/Wi-Fi mobile phone.

MobileVoIP turns the Internet into a large mobile roaming network, creating an opportunity for mobile carriers and service providers to offer feature-rich and improved service levels that take advantage of Internet economics. Sipura's and BridgePort Networks' plans to develop a tightly coupled MobileVoIP solution will enable mobile operators and other service providers to offer MobileVoIP solutions for fixed-mobile convergence or fixed-mobile substitution bundles to subscribers.

"One of the key propositions of MobileVoIP is the ability for service providers to offer end users lower cost services with greater flexibility and better quality of service," said Jan Fandrianto, president and CEO of Sipura Technology. "By working with BridgePort Networks, we're helping to bring the worlds of mobility and VoIP together so that end users will benefit from the economics and conveniences of MobileVoIP."

BridgePort Networks' solutions, based on the NomadicONE NCG, are the industry's leading platform for MobileVoIP convergence. The solutions bridge cellular roaming technology compatible with mobile networks (including GSM, CDMA and 3G) and VoIP based on the open SIP (Session Initiation Protocol) standards. Based on open standards, the solutions bridge signaling, call control and authentication between the SIP based VoIP world and the SS7 based core mobile network, cost effectively delivering mobile services over VoIP networks and VoIP calls to mobile phones.

"This relationship with Sipura marks a leap forward for MobileVoIP by enabling us to offer service providers a broad range of device options for end users," said Mike Mulica, president and CEO of BridgePort Networks. "Our diverse device approach allows all operators to immediately go-to-market with an offering that maps to specific communications user segments."
