Founded in May 1998, ESTOS is continuing to create innovative products in the field of telecommunications. A current ESTOS sphere of influence is the abstraction of complex interfaces in the sections of Office Integration (OI) and Computer Telephony Integration (CTI). ESTOS is developing electronic components for data management, driver software for PBX-producers and professional application software for client-server systems.

By using the slogan 'Successful Communication', ESTOS offers innovative and application-proof communication solutions to its clients in a transparent way. Simple installation, easy handling and professionalism are the most important characteristics of ESTOS products. In addition, ESTOS provides competitive solutions to support and product services. It is mandatory for ESTOS to optimize its delivery service and client support.

ESTOS products rank with the best in the business. This is due to the continuous perfectionism of the ESTOS philosophy and its developers’ spirit of innovation. ESTOS always strives to improve and develop its products. This includes proposals for improvements we receive from users. The ESTOS homepage www.estos.de resp. www.estos.com offers current product information, technical support and download test / buy opportunities. Updates and patches are also available in the same way.

In Germany, ESTOS established its name by its product PABX Monitor, a configuration and monitoring program for GTB and Telebau PBX-systems. Outside Germany, ESTOS made its name by developing EuriTel software, a service and telephony software for Ascom ISDN telephones.

By making use of modern technology, the ESTOS pioneers played a leading part in spreading TAPI standards all over Europe. ESTOS has developed extensive driver software for PBX-producers, which promotes CTI on a wider level.

By introducing ProCall telephony software for MS Outlook, ESTOS succeeded in establishing international contacts, an important step in achieving its product certification by Microsoft. The MS Outlook/Exchange solution ProCall once more enabled ESTOS to set new standards by adding another specialist domain to those already achieved in the field of CTI - Office Integration (OI).

In the PBX-system section, ESTOS introduced its latest innovation, a network TAPI Driver for Siemens Hicom systems, a driver software ready to implement the complete CSTA functionality. Subsequently, ESTOS and Siemens decided to officially authorize its HICOM Ready partnership.
