InfPort43 effectively supports telecommunications providers in fulfilling their legal obligations (such as exchanging porting data with other carriers in landline and mobile sectors). In addition, it operates interfaces for the automation of ordering processes (such as WITA for ordering lines from Deutsche Telekom). To round out our system, there are modules for enhancing performance or saving costs.

Since the deregulation of the telecommunications market in 1998, carriers must fulfill a series of tasks required by law. For example, they are obligated to exchange porting data for landline phone numbers on a daily basis with all other carriers, so that the subscribers to numbers can be reliably determined. What they need is a solution that is simple to use, performant, reliable, economical, and easily integrated into the existing system landscape.

Our solution: InfPort43

InfPort43 initially served as a porting database which carriers could use to both publish and receive information about requested or completed phone number porting transactions. Conflicts over variances or errors in the reported data can be resolved. Further, recurring business processes are performed automatically, to avoid errors and save costs.
Along with the growing challenges, we’ve expanded the range of functions offered by InfPort43 dramatically. Each new functionality is implemented in the form of a new module; altogether we’ve created an extensive module library.
The modularity of InfPort43 allows our customers to assemble a program package to meet their specific needs. All functions may be accessed via web services from the customer’s own customer care system. This makes it easy to integrate InfPort43 into an existing system landscape. Should it be inconvenient to interface any particular module with the customer’s own system, there is a web client available that covers the full range of functions in each process.

Once you’re in, you can use it in so many ways

The porting data consolidated in the database can also be used for other purposes, for example, least-cost routing.
