Professional CTI and TAPI middleware

The ECSTA series, i.e. estos professional TAPI driver, enables communication between the telephone system and the IT infrastructure. estos ECSTA for Broadsoft delivers a Telephony Service Provider (TSP) for Microsoft® Tapi 2.1 (also 2.2 and 3.0).

This Tapi driver establishes a central communication between a PC/Server and the telephone system, adopting Broadsoft OCI-C and OCI-P protocol.

Workstation mode

ECSTA is installed on a single computer and directly connected to the Broadsoft platform providing native and standard TAPI to any local application. 

  • Easy to set up

  • Instantly up & running

  • Simplified topology



Server mode

ECSTA is installed on a Server environment and can be configured to control multiple extension at once. Such configuration allows for a server-side 3rd party TAPI-compliant application to work server side.

More complex scenarios may still require TAPI on each workstation; combining ECSTA with estos UCServer TAPI Lines middleware allows for centralized single-workstation TAPI configuration, deploy and maintenance. It also supports virtualized desktop environments where TAPI, due to its computer-based configuration, would normally be impossible to set up.

  • Centralized configuration (with AD auth support)

  • Seamless TAPI emulation

  • Virtualized desktop (e.g. Citrix XenApp or MS Remote Desktop Services) support
