Introduction

estos ECSTA for OpenScape Business makes several Telephony Service Providers for Microsoft® TAPI 2.1 (and 2.2 and 3.0, as well) available. These TAPI drivers create a central communication system between a server and the telephone system. All telephone system devices are available on this server as TAPI lines.

All estos ECSTA for OpenScape Business drivers use the efficient CSTA interface in order to communicate with the telephone system.

For the installation and management of the driver see Driver Management.

^*A CSTA middleware solution is required for the integration of these telephone systems. This middleware will is be integrated either as hardware in the telephone system (OpenScape Business UC Booster Card) or as software on a SUSE Linux operating system (OpenScape Business UC Booster Server) . You will find detailed information about both options and their installation on the UC Booster Platforms page under OpenScape Business.

Using the driver in the network
After installing the driver, you may use all configured line devices on the server as TAPI-lines. If you are using a server based CTI Software, you may install it now. To have the TAPI-devices available on all workstations, the TAPI-driver must be distributed in the network. There are the following options:

1. estos UCServer
   The estos UCServer is a CTI/UCC server software which distributes the telephony information across the network using a graphical client or a multi-line TAPI driver. Workgroups, domains, Active Directory® and Terminal Server are supported.
2. estos CallControlGateway
   The estos CallControlGateway for Lync/OCS is a gateway that connects the TAPI-lines with the Lync/OCS server. This enables the Lync/OCS client to use traditional telephone devices via Remote Call Control (RCC).
3. Windows® Telephony Server
   The Windows® Telephony Server is a component of Windows® server operating systems since Windows® NT. You will need a domain. The service is limited to domain users.
