The estos "Multi" strategy – vendor-independent and flexible

Distributed locations, different telephone systems and multiple end devices - the requirements for well-functioning communication between employees and with customers are high. The flexible workplace has gained in importance in recent months, hybrid working is fully in vogue and will also accompany us in 2022.

Stay flexible!

The estos "Multi" strategy enables location and vendor-independent communication, optimizes collaboration among your employees, and ensures uncomplicated exchange with business partners and customers. 

The "Multi" strategy team introduces itself:


Do you use different telephone systems from various manufacturers? Whether from the cloud or on-premises: With the MultiVendor concept you integrate them into one application. As middleware, our professional TAPI drivers of the ECSTA series enable communication between the different telephone systems and the Microsoft Windows world. This is how you create the basis to control your telephony via the PC


Several branches, several PBXs, and just one UCServer – this is also possible: MultiSite enables the connection and integration of CTI, unified communications and unified messaging across different locations. By networking with the ECSTA series, the presence status and contact information can be exchanged and communicated via text and audio/video chat, regardless of location.


Our UC & CTI software suite ProCall Enterprise combines all important communication channels in one application and can be used platform-independently and across devices. Whether Windows, macOS, IOS or Android - the MultiDevice principle of ProCall Enterprise enables flexible communication in the office, at home and on the move.

Hybrid working requires networked collaboration across company boundaries. With the vendor-independent software from estos, you remove barriers and open up new possibilities.
