"... products that are used by more than one million users in companies every day."

Since 1997, estos has been developing communication software in Starnberg. estos has succeeded over the years in continually presenting products in an extremely dynamic market that are used by more than one million users in companies every day.

One of the main reasons for our success until today is the ability to recognize trends very early and take an active part in emerging technologies with innovations.

The first ten years were characterized by the merging of the computer and telephony world (CTI). In the current decade, the topics of networking (Federation) are relevant as well as, in the future, the increasingly use of audio/video (WebRTC).

estos partners and customers appreciate the extremely easy handling of the software, the professional image and the passionate commitment of the estos team. Numerous awards and a high rate of recommendations prove this.
