NexTone has announced that SITA has deployed NexTone’s session management technology for the company’s Voice Exchange service.SITA’s Voice Exchange service enables VoIP traffic - whether originated by an IP-based end point or media gateway - to be optimally routed based on an ENUM (the mapping of a telephone number from the public switched telephone network (PSTN) to Internet functionalities) response and geographic location of the receiving or target end point. The service’s policy is to allow subscribers to access their service no matter what type of network used - VPN, public Internet, or airline partner network.
Utilizing NexTone’s Multiprotocol Session Exchange’s (MSX) advanced session border control functionality, SITA’s Voice Exchange enables its customers (airlines, aircraft manufacturers, airports, airport authorities, aerospace companies, and travel agents) to securely and easily peer with one another over a common global network. SITA’s service enables these customers to bypass the traditional PSTN; link islands of distributed locations together into one common service; significantly reduce the costs of intra- and inter-airline telephony costs; and integrate with existing SITA IP-based infrastructure and related services.
NexTone’s intelligent session border controller, with embedded session management technology, not only allows SITA to introduce new services such as voice VPNs and IP-Centrex to their existing customer base, it also addresses management issues and the complexities, namely latency and jitter, associated with IP networks to ensure consistent QoS for real-time VoIP sessions. In addition, SITA leverages NexTone to authenticate and authorize subscribers, as well as differentiate which access network is being utilized and apply different QoS policies based on this information.
NexTone enables SITA to provide and deliver simultaneous hosted IP telephony and SIP Trunking services that are offered to SITA’s community of air transport industry customers. These capabilities include service and user mobility; security; centralized dial plan management; SIP Trunking with media steering; IP PBX interoperability and interworking; and SLA and QoS threshold management.
Denis Berger, head of product line, SITA - “We needed a scalable solution that could integrate different protocols, while at the same time fix signaling variations for interoperability. NexTone’s MSX and RSM products not only meet these interoperability requirements, but further extend the overall quality of SITA’s voice and convergence services. Today, members of the Air Transport Industry can now call and be called on the Voice Exchange community without any per minute charge. Calls can be made from any device, including IP Phones (hardware), PC or PDA/smartphones, dual GSM/Wi-Fi mobile phones, or legacy PBX telephones.”
Dan Dearing, VP of marketing, NexTone - “Service providers and enterprises are rapidly adopting VoIP peering to interconnect their VoIP and IMS networks. SITA is at the forefront of this networking phenomenon. NexTone’s intelligent SBC technology provides SITA with VoIP policy management and enforcement capabilities to ensure guaranteed service delivery, geographic service redundancy, and overall network performance within their peering environment.”
