New customers for the Next-Generation-Network of 3U TELECOM GmbH

  • International companies launch their subscriber network in Germany

Marburg, 23 March 2023 – Two international telephone companies are now using the Next-Generation-Network (NGN) of 3U TELECOM GmbH, a wholly owned subsidiary of 3U HOLDING AG (ISIN DE0005167902). A company from Austria and a group based in Paris can now realise German telephone connections for the expansion of their business operations in Germany and thus save time and costs for themselves and their customers. The offer of a virtual subscriber network (vSN) is based on the powerful and proven NGN infrastructure of 3U. 3U TELECOM thus saves its customers high investments in their own NGN hardware and software, in their own telecom interconnects and the extensive interconnection tests with Telekom Deutschland. The new customers also use 3U’s number management and porting database.

One customer, the company founded in France in 2014, offers its more than 12,000 medium-sized customers worldwide a comprehensive and high-performance cloud-based telecommunications platform, especially for sales and customer care. It will now also intensify its internationalisation course in Germany and has just opened a new office in Berlin. Already, 30 German-speaking employees support customers and technology partners in the DACH region.

The Vienna-based, family-owned company has specialised exclusively in business communications for two decades as a telecoms network operator and solution provider, offering enterprise customers comprehensive and reliable telephony solutions from the cloud – from local and international customer hotlines to cloud PBXs and customised telephony solutions. The international orientation has been part of the business model from the very beginning and has led to a broad customer base throughout Europe.

Uwe Knoke, member of the 3U Management Board in charge of Strategy and Business Development at 3U HOLDING AG, welcomes the new NGN customers: “We are pleased that leading international telephony providers rely on our network and our comprehensive range of services for their German business. The NGN is a technical backbone of our growth strategy in the 3U TELECOM area. The increased expansion of marketing, sales and customer orientation should further accelerate this upward trend that is now emerging.”
