Blackout-Proof Voice over IP

With BEUL to a comprehensive enterprise solution concept

A German power utility company modernized its internal business telephony, a decentralized, historically grown PBX system network. Company telephony enables employees in substations, power plants and network control centers to communicate to restore network operation in the event of a blackout, independent of public telephone or mobile networks. The availability and ability to act of the network control centers is an essential prerequisite for the operating license from the Federal Network Agency (Bundesnetzagentur) and forms the business basis for the company as an operator of critical infrastructure (KRITIS).

Together with BEUL, a comprehensive enterprise solution concept was developed and implemented that, in addition to IP-based voice services, also provides video and messaging and offers maximum availability and information security. This was achieved through geo-redundancy, hardware clustering and the use of multi-level fallback mechanisms.

We accompanied the customer throughout the entire project lifecycle, from the first design workshops, through proof-of-concept and rollout, to technical documentation, training and operational support.
