The future-proof communication solution from the cloud
CCS is an open source-based hybrid cloud PBX telephony system for use in the carrier sector. Our solution helps operators not only to be access providers, but also to act as service providers with value-adding services on the market.
Through seamless integration into core systems and Unified Communications as a Service (UCaaS), we achieve native convergence between fixed and mobile networks and UC services, thereby creating optimised communication processes.
Our Cloud Communications Service supports CISCO Enterprise Endpoints. An intuitive and user-friendly user interface enables simple operation without the need for external technical experts.
Your advantages as a service provider
- Secure USPs in conjunction with your strengths as a carrier
- CCS can be integrated into your core systems as well as into UCaaS environments.
- CCS can be used as a standalone system or complement UCaaS and mobile carrier offerings
- You remain independent of large international providers in terms of licences and operations

Cloud Communication Service consistently relies on open source and a scalable Kubernetes architecture. Service providers can use it to provide their customers with a modern platform for telephony, video conferencing and chats across all devices.

Telephony and Unified Communications

Fully integrated
Carrier integration
CCS is deeply integrated into carrier provisioning processes. This simplifies operation and increases efficiency without compromising compatibility.
Microsoft Teams
Seamless integration with Microsoft Teams enables communication directly from the collaboration solution.
- Start calls to landlines or mobiles from Teams
- Receive calls from the landline or mobile network directly on the Teams client
- See whether the partner is currently on the phone via presence status in Teams

Open source as a basis
CCS is based on an open source unified communications platform. This creates the necessary flexibility to customise the solution to the needs of the service provider and integrate it into the systems.
- Independent of third parties
- Calculable costs
- Continuous expansion
- Strong developer community

Scales perfectly
CCS utilises a modern Kubernetes architecture that is designed for a high degree of scaling. This provides optimum support for daytime-dependent loads as well as growth in customer and user numbers.
- Cost-efficient and resource-saving operation
- Configurable per service and customer
- Automatic provisioning of virtual resources
- Usage-dependent and granular deployment

Extensive API
CCS provides full API control to customise the system to the specific requirements of companies and integrate it seamlessly into their existing infrastructure. All functions that can be used via the front end are also available programmatically via the API.
Example calls:
- Manage clients, users and telephones
- Call queue management
- Call forwarding


Maximum flexibility
One of the many strengths of our Cloud Communication Service is its great flexibility. Companies can choose exactly the functions they need and activate them on a per-client basis.
This unique billing process ensures that customers only pay for the services they actually use. This makes CCS a very cost-effective and highly customisable system for seamless and efficient communication.
Our many years of experience in the development and operation of highly scalable and business-critical applications guarantee the high availability and future-proofing that users and operators rightly expect from a modern UC solution.
CCS is a standardised solution that ensures consistency and reliability across all communication channels.
CCS offers integrated, powerful tools for monitoring and operation. These tools allow companies to proactively manage and optimise analysis and troubleshooting processes.
CCS includes an intuitive and user-friendly portal for self-maintenance, which relieves the burden on IT support in the long term.
We offer each operator customised services and support models that are precisely tailored to their needs.


We help providers to remain competitive in the hotly contested communications market by helping them to reduce costs, generate stable revenues and strengthen customer loyalty. We do not position ourselves as a technology supplier, but work actively and strategically as a partner.
We support service providers in building and maintaining strong relationships with their customers, thereby generating additional dynamic revenue streams.
Our solution is designed to significantly reduce the costs of service providers, e.g. by reducing dependencies on large commercial providers.
We offer exceptionally affordable licence fees that enable service providers to sell our solution to their customers with high profit margins. This makes it easier for operators to achieve their EBITDA targets.
