Since 1997 we have developed Unified Communications & CTI software for communication for companies. The foundation of our success to this day is recognizing trends as early as possible and to use them to design innovative products.


"The favourite feature is definitely the good Outlook integration that I can really see immediately which customer or whether a colleague is calling," says Juliane Jann, network administrator at IT Verbund Uelzen.

The " IT-Verbund Uelzen" looks after the IT of most surrounding communities and has introduced a communication solution with estos software products, such as ProCall Enterprise, for its customers.
