SITA Deploys NexTone's Session Management for Airline Voice Exchange

SITA, which operates the global network serving the air transport industry, has deployed NexTone's session management technology for the company's Voice Exchange service.



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. The 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.



NexTone's intelligent session border controller, with embedded session management technology, 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.
