OpenScape Business V1
Sales Information Page 43 04.06.2013
The protection of the CSTA interfaces against abuse has been improved. The access
mechanism has been revised.
The provided CSTA functions have been expanded. Detailed descriptions can be found in the
OpenScape Business CSTA Interface Manual.
The CSTA Phase II protocol is no longer supported.
CSTA applications to be used with OpenScape Business should be tested and released in
conjunction with OpenScape Business.
Supported Devices
The devices listed in section
1.2.9 can be controlled via the CSTA protocol. However, the
functionality provided via the CSTA protocol is highly dependent on the respective terminal
equipment as well as the device interface.
System telephones with TDM or IP/HFA interfaces offer the most functionality, and ISDN devices
offer the least. Devices based on SIP and DECT occupy a special position with regard to the
available functions.
Detailed descriptions of the supported devices and the supported features can be found in the
"CSTA Interface Manual" for OpenScape Business.
In addition to the listed devices, the following system resources can be accessed via CSTA:
– CO trunks
– Virtual stations
– UCD groups
– MULAPs
Connections to the CSTA Interface
The OpenScape Business CSTA interface supports a maximum of 4 CSTA links for connecting
external and internal CSTA applications (running within OpenScape Business). These
applications must share the available CSTA links. In the default factory state of OpenScape
Business, the following preassignments are preconfigured for the CSTA links, which sufficient for
most use cases:
1 free CSTA link available for connecting an external CSTA application
1 CSTA link preassigned for the internal connection of the OpenScape Business UC Suite
If the OpenScape Business UC Suite is not required due to the use of UC Smart, for example,
the assigned CSTA link can be used elsewhere.
1 CSTA link preassigned for the internal connection of the CSTA Message Dispatcher
(CMD)
If not TAPI 120 Service Provider is being used at the system, this CSTA link can be used for
connecting other external applications.
1 CSTA link preassigned for the internal connection of the Direct Station Server (DSS)
The DSS server is used only for networked OpenScape Business systems. In standalone
systems, the preassigned CSTA link can be used for other purposes.
If multiple external CSTA applications need to be connected, it must be checked which internal
applications are not required. The CSTA links occupied by these applications can then be used
for connecting the external CSTA applications.
Info
OpenScape Business TAPI 120 is always connected at the CSTA link preassigned for the CSTA
Message Dispatcher (CMD) and does not count in the above sense as one of the external CSTA
applications. OpenScape Business TAPI 170, by contrast, must be connected as an external
CSTA application.
Connection of External CSTA Applications to a Standalone OpenScape Business System
The CSTA applications are connected to the CSTA interface of OpenScape Business over the
LAN.
For this connection, one CSTA link of OpenScape Business is required for each CSTA
application. No licenses in the OpenScape Business system are required for this purpose.
However, the model-specific prerequisites for the operation of the CSTA interface must be taken
into account.
