In this project we are building a completely new operational communication system in the safety-critical railway environment.

The end-user equipment consists of a touchscreen terminal running a user interface, based on modern web technology (React).

The user interface should be very flexible and adaptable to the needs of the end user. An (existing) proprietary hardware, which also has a small web-based user interface, is used as audio device. 

The backend is designed as an application server that is integrated into the customer's Kubernetes environment. For voice communication, the end-user terminals are integrated into an existing IMS using SIP, specific railway functions (e.g. special call routing) are implemented using the appropriate application server.

The activities for the Scrum Team include the development of essential parts of the user interface including the required backends, as well as the development of the corresponding IMS application server for the rail-specific voice communication functions.
