**About the project**
Communication is a first-class citizen to enable business success! To enable a company’s communication, we develop a modern cloud-based telephony system for the Austrian market. The integration of traditional telephony technologies and modern requirements such as scalability is the key factor for market success.   The system should take well-acknowledged industry tools such as Asterisk or Kamailio and bring them to the modern world of clouds and virtualization, customizable with a modern UI. At the end of the project’s journey, we will migrate an already established platform with several thousands of customers to the new platform and enrich it with additional services such as MS Teams or Zoom integration.
