Policy and Routing Software Edition (PSX SWe)

The PSX SWe is the virtual, cloud-native version of our centralized policy and routing solution. It provides intelligent session control for VoIP services on SBCs, media gateways and call controllers. The PSX SWe can be deployed in any service provider’s traditional or IMS network.

Fitting seamlessly into a service provider virtual and cloud strategy, PSX SWe can be deployed as a virtual network function (VNF) in multiple private or public clouds. On a private cloud, PSX SWe can be implemented on OpenStack orchestrated by Ribbon’s VNF Manager. Alternatively, PSX SWe can be implemented on Amazon Web Services.

PSX SWe applications address least cost (LCR) routing, quality of service (QoS) routing, number translation services, deployment as an IMS Breakout Gateway Control Function (BGCF)and act as a broker for STIR/SHAKEN and Reputation Scoring services used to mitigate robocalls.

The PSX is a standards-compliant, multi-protocol solution providing a call routing engine that works seamlessly in heterogeneous voice networks supporting SIP, ENUM, H.323, TDM, SS7/C7, and IN/AIN.

Least Cost & QoS Routing and Number Translation Services

PSX SWe delivers an enhanced Least Cost Routing (LCR) application enabling service providers to reduce costs and increase quality of service by selecting the most appropriate SIP session routes based on a variety of criteria including interconnect carrier rates, service level agreements, voice quality, latency and network capacity. Because of the complexity of LCR calculations and the number of variables involved, this decision-making process has traditionally employed teams of analysts or been addressed by LCR engines. Instead, Ribbon’s LCR application is offered as a highly scalable and flexible solution that works seamlessly with Ribbon, or 3rd party SBCs. The LCR application aggregates pricing and customer information from back-office systems and combines it with near real-time SIP session metrics provided by Ribbon network analytics software to optimize policy decisions.

If you want to find the shortest path between two points, simply draw a straight line. If, however, you want to find the path with the lowest cost AND the best quality of service (QoS), it can be anything but simple and straightforward. By combining PSX SWe and Ribbon Analytics, we can offer QoS Routing making it possible to find the best combination of cost and quality when determining a routing path. With the QoS routing application a service provider gains a competitive advantage to be the first choice for routing SIP interconnect and access trunk traffic.

When network operators support number portability services it costs them a very small fee to “dip” into a third-party number portability database for an address. Although the fee may only be a fraction of a penny for every dip, if you handle millions of calls these number translation fees add up fast. Fortunately, with the PSX SWe there a better way - host your own number translation server. The PSX SWe number translation application enables carriers to deploy a number portability server in-house, reducing costs and decreasing per-call latency incurred from external 3rd party database dips. Like LCR, it is a highly scalable, highly flexible solution. The number translation application supports interoperability with multiple databases using SIP, ENUM, INAP, and TCAP allowing service providers to get number portability data directly from the source.
