Reducing costs and Improving efficiency for number portability lookups is as easy as 1-2-3. With the Sonus Number Portability (NP) solution, carriers and service providers can address the growing need for number portability services while reducing costs. This is available as a software-based feature upgrade to the PSX Centralized Routing and Policy Server and delivers a highly scalable, highly flexible number portability solution. The Number Portability solution includes both PSX and DSC products to support SIP, ENUM and SS7 signaling protocols with interoperability to a variety of databases using SIP, ENUM, INAP, and TCAP. With this solution, carriers can get number portability information directly from the data source and host it on-board the PSX instead of paying a fee to a third-service for every dip. Carriers can reduce costs and eliminate 100-200ms of latency per call by dipping directly into their own number portability server.
Because the PSX provides a centralized signaling, routing and policy function across both SS7 and IP signaling protocols it makes it easier to manage NP across multiple network types and to seamlessly transition from one protocol to another protocol in the future.
