Overview

For service providers around the world, voice over broadband has quickly become an exciting new application that is redefining how voice services are delivered to subscribers. By enabling the delivery of voice services over highspeed cable or DSL lines, service providers can now offer next-generation voice services that are truly integrated with the Internet, allowing subscribers to personalize and customize their voice services via a standard web browser. For competitive service providers, voice over broadband allows them to access end users without the upfront capital expense typically associated with a network build or the cost of leased lines from incumbent carriers.

Business Need

For all service providers, the overarching business driver is how to stay competitive by quickly attracting and keeping new customers. To achieve this goal, service providers looking to enter the voice over broadband market need to deploy flexible and reliable solutions that allow them to deliver a broad range of innovative voice services with a pragmatic, pay-as-you-grow architecture that provides a reduction in overall telecommunications costs. In addition, service providers need to understand that, with the proliferation of voice over broadband offerings, subscribers can change their service providers much more quickly than before. If the service has poor call quality, is unreliable and doesn’t evolve regularly to support innovative new voice features, subscriber churn is certain to occur.

sentitO’s Solution

sentitO Networks provides a highly-scalable, secure and reliable voice over broadband solution that cost-effectively allows service providers to roll out competitive voice over broadband services today while putting in place a
complete service delivery framework for the ongoing rollout of innovative new services to eliminate subscriber churn. sentitO’s Open Network Xchange (ONX) product portfolio is the first-and-only solution purpose-built from the ground
up for carrier-class VoIP deployments. Custom hardware that’s globally certified and an open and distributed architecture based on industry-standard SIP and XML combine to create the most flexible, secure, scalable, and reliable VoIP solution available today. Service providers can leverage SIP and XML to ensure interoperability and accelerate time-to-revenue with voice and enhanced SIP services and reliably deliver those services over the Internet and/or private IP networks.

The ONX consists of the following carrier-class products:

• The Intelligent Voice Gateway (IVG) is a purpose-built, SIP-based media gateway that performs Time Division Multiplexing (TDM)/IP conversion processing, call control and call routing. It combines the functions of a media gateway, a router and a service broker to create a more efficient and secure solution purpose-built for VoIP networks.

• The Proxy7 Signaling Gateway uniquely combines a Session Initiation Protocol (SIP) proxy server with SS7 signaling intelligence to create the most cost-effective bridge between emerging VoIP networks and the PSTN. It enables intelligent and scalable SIP/SS7 interworking to support transparent configuration and management of services across-and- between IP and TDM networks.

• The PreVision Network Manager is an integrated, real-time carrier-grade management platform for seamless and simplified billing, management and administration. In addition to the ONX products, sentitO provides a wide range of certified partners to round out a turnkey voice over broadband solution, including application servers, session border controllers and SIP endpoints. Because sentitO’s ONX natively incorporates industry-standard SIP and XML scripting for partner interworking, the time to deployment and revenue is dramatically decreased.

Benefits

• sentitO’s ONX speeds time to deployment and revenue through native SIP and XML scripting and interworking with partner products
• The IVG uniquely incorporates enhanced security features, such as Denial of Service (DoS) and Access Control Lists to prevent malicious attacks, such as SPIT (Spam over Internet Telephony) and ping floods to a service provider’s network and subscribers
• The ONX constitutes an advanced service delivery framework, capable of interoperating with multiple feature server elements, including Asterisk™, to ensure consistent service innovation, decrease subscriber churn and increase average revenue per user
• The IVG provides wire-speed routing of voice bearer paths for unmatched voice quality and reliability across disparate networks
• The ONX’s open and distributed architecture enables service providers to distribute up to 5 IVGs per each Proxy7 signaling gateway to reach a wider customer base and to provide secure local handoffs to the PSTN
• With no common or pooled DSP resource cards, the IVG enables a true ‘pay-as-you-grow’ model for traffic and service deployment.
