Many CTI and CRM applications on the market use the Microsoft TAPI interface for connecting to the telephone system. With OpenScape Business TAPI 120 V1 and OpenScape Business TAPI 170 V1, two new and powerful TAPI Service Providers (TSP), which are optimized for the system architecture and network topology of OpenScape Business, are now available for connecting TAPI-based applications in addition to the CallBridge Collection.
The choice of the appropriate TAPI Service Provider essentially depends on the number of client PCs to be connected with TAPI applications as well as the existing IT infrastructure and the phone devices used.
is used as a traditional first-party TAPI Service Provider on system terminals that have a LAN or USB interface. It is suitable for installations with just a few PCs. A LAN is not necessary for the operation of the CallBridge Collection. The CallBridge Collection is installed on each PC that is running a TAPI application. Analog, Cordless and system devices without USB/IP interfaces are not supported. TAPI connections via the CallBridge Collection are not licensed
is used as the preferred first-party TAPI Service Provider in Microsoft networks with or without a domain controller when analog, Cordless and system devices without IP/USB interfaces are also to be operated in conjunction with TAPI applications. The TAPI 120 Service Provider is installed on each PC client that is running a TAPI application. Connections via TAPI 120 are subject to licensing within OpenScape Business. To connect to OpenScape Business, only one CSTA link is required, regardless of how many TAPI 120 clients are being operated.
is a classic "third-party" TAPI Service Provider that is installed on a server on the LAN and connected centrally to the OpenScape Business System. TAPI 170 can be used as an alternative to TAPI 120 if there is a domain controller in the Microsoft network. When using the so-called remote TAPI function, it is not necessary to install the TAPI Service Provider on the client PCs. This offers significant time savings in installations with many client PCs.
Please note, however, that the use of OpenScape Business TAPI 170 is mandatory in the following constellations:
- Connection of TAPI stations in networked OpenScape Business systems when the TAPI stations are located in different nodes.
- Connection to TAPI applications running on a terminal server
- Connection to server-based TAPI applications
OpenScape Business TAPI 170 is subject to licensing within OpenScape Business. To connect to OpenScape Business, one CSTA link is required, regardless of how many TAPI 170 stations are being operated.
