The ever-increasing and more complex interlinking of technologies and services poses a key challenge for companies in both the commercial and public sectors. External influences on data and IT processes must be limited as far as possible and national regulations must be complied with. Sensitive data must be protected in the best possible way and companies are required to regain control over their processes and infrastructures. These developments also affect Unified Communication systems - because what was considered cost-effective cloud communication yesterday may become a security risk or a money trap tomorrow. We are already working intensively on this topic and offer robust, forward-looking solutions for digital independence.
CCS - an Austrian innovation for sovereign UC systems
With our Cloud Communication Service (CCS), we have developed a comprehensive response to these challenges and set new standards. The hybrid cloud PBX system combines landlines, mobile phones, MS Teams and European collaboration solutions such as OpenTalk into a standardised platform and offers data sovereignty:
- 100% transparency through open source foundation - no hidden dependencies
- Control over all communication data and processes - no transfer to third countries
- Full cost control through pay-per-use model without external licence dependencies or price dictates from large manufacturers
- Strategic independence from geopolitical developments
- Long-term planning security without vendor lock-ins
True digital sovereignty in corporate communications means not only data protection, but also complete control over your own UC infrastructure
Secure your digital sovereignty!
Telephony and Unified Communications

International recognition confirms innovation leadership
Our innovative solution impresses leading international experts: At AstriCon 2025 in Florida, the SLAC (Secure Linux Administration Conference) and the Kamailio World Conference in Berlin, Georg Rinnhofer and Florian Lechner presented the CCS approach to experts from various tech communities.
The successful combination of an open source basis for data sovereignty and modern Kubernetes-controlled cloud architecture for optimal control and load balancing attracted particular international attention. The result is a UC solution that gives organisations complete control over their communication data and at the same time makes them independent of external providers.


The feedback from the international tech community shows that our solution is not only relevant on the domestic market, but is also setting new standards globally. Further proof that our innovations "Made in Austria" can hold their own internationally and offer real alternatives.
Proven in large-scale use: thousands of connections as proof
Our solution is not just a concept, but years of proven practice. Over 80,000 connections prove its suitability for robust scalability. The ongoing successful migration from the original Cisco-based HCS solution to the open source CCS system shows that it is possible to switch to complete vendor independence - even for critical communication infrastructures during ongoing productive operations.
The proven technology has also been available to new customers since the beginning of June 2025, enabling organisations of all sizes to switch to sovereign communication solutions. Data sovereignty is THE key issue for companies in the very near future. With our Cloud Communication Service, we offer the technology and expertise to realise this indispensable security factor today!
