Connectivity

The OpenScape Business TAPI 170 software is installed on a Microsoft Windows server on the network. The connection to OpenScape Business occurs via a CSTA link. A physical connection between the Windows PC and the phone is not required.
OpenScape Business TAPI 170 can be set up in different operating modes on single node systems or in the OpenScape Business network.

Connecting server-based TAPI Application to OpenScape Business using TAPI 170

The server applications and the TAPI 170 software are installed on the so-called "Telephony Server" in the network. The server applications provide their associated clients in the network with telephony features for stations that are configured within OpenScape Business TAPI 170. The TAPI 170 software is connected to the CSTA interface of OpenScape Business over the LAN.
For this connection, one CSTA link of OpenScape Business as well as one TAPI license for each configured TAPI station are required.

Connecting Client-based TAPI Applications to OpenScape Business using TAPI 170

In this scenario, the OpenScape Business TAPI 170 software is installed on a server on the network. On the client PCs with the TAPI applications, the so-called "Remote TAPI" function is enabled, via which the TAPI application on the client communicates with the TAPI 170 SW on the server. No TAPI 170 software needs to be installed on the client for this purpose. The TAPI 170 software is connected to the CSTA interface of OpenScape Business over the LAN. For this connection, one CSTA link of OpenScape Business as well as one TAPI license for each configured TAPI station are required.

Connecting Terminal Server-based TAPI Applications to OpenScape Business using TAPI 170

In this scenario, the client-based TAPI applications are installed on one or more terminal servers. In this case, the TAPI 170 software is also installed on the terminal server. In the case of a cluster consisting of multiple terminal servers, the TAPI 170 software must be installed on each terminal server in the cluster. Each instance of the installed TAPI 170 software is connected to OpenScape Business over the LAN. For each instance of the TAPI 170 software installed on a terminal server, one CSTA link of OpenScape Business is required. In addition, a TAPI license is also required for each configured TAPI station.
Note The number of terminal servers that can be operated in the cluster is limited to the number of free CSTA links available within OpenScape Business for connecting the TAPI 170 software. This should be checked and taken into account before marketing.

Connecting TAPI 170 to Networked OpenScape Business Systems

For networked OpenScape Business systems, the TAPI 170 software is installed on one server, which is connected via the LAN to the CSTA interface of the master node. This connection is independent of the previously mentioned operating modes of the TAPI 170 Service Provider (remote TAPI or server-based connection). To implement this connection, one CSTA link of the OpenScape Business master node as well as one TAPI license for each configured TAPI station are required.
Note Via the master node, the TAPI 170 receives network-wide access to all stations in the network. If the TAPI 170 is connected to a slave node instead of the master node, TAPI 170 can access only the stations of the slave node. When using multiple TAPI 170 in a terminal server cluster, one CSTA link to the master node is required for each TAPI 170.

Capacities

The maximum number of TAPI 120 client PCs that can be connected to OpenScape Business depends on the model. More information on this can be found within the OpenScape Business Sales Information.

Compatibility

Supported Systems

• OpenScape Business X3
• OpenScape Business X5
• OpenScape Business X8
• Open Scape Business S

Supported Devices

TAPI 170 supports the same devices as the OpenScape Business CSTA interface.
These are described in section 1.6.11, "CSTA Interface".

Prerequisites

For operation of OpenScape Business TAPI 170 some HW / SW prereqisites have to be fulfilled

HW/SW prerequisites

Computer HW

The PC hardware must comply with at least the system requirements specified by Microsoft for the operating system used, provided that no further software applications other than TAPI 170 are being operated. In addition, an Ethernet LAN interface is required.

Computer SW

Operating systems

• Microsoft Windows Server
  • Microsoft Server 2008 R2, 64 bit
  • Microsoft Server 2012, 64 bit
  • Microsoft Small Business Server 2011
  • Microsoft Small Business Server 2012 (essential)

  • Microsoft Windows 7 (Ultimate, Professional)
  • Microsoft Windows 8 (Pro, Enterprise) not Windows RT
  • Microsoft Server 2008 R2
  • Microsoft Server 2012

Note
In addition to the license for the server operating system, the Microsoft licensing model requires Microsoft device or User CALs corresponding to the number required for the planned expansion. These CALs are not included in the delivery of OpenScape Business TAPI 170 and must be purchased separately.
Under certain conditions specified by Microsoft, a "Windows Server for embedded systems" with the so-called "embedded Telco license" can be used for OpenScape Business TAPI 170.

OpenScape Business

In order to connect to OpenScape Business TAPI 170, one CSTA link of OpenScape Office is required, regardless of how many TAPI 170 clients are connected. This also applies to networked OpenScape Business systems. Connection to a CSTA link requires either UC Booster Card or UC Booster Server

Documentation

Some documents in various languages are available for OpenScape Business TAPI 120. As there are:

• Installation manuals
• Technical release note

The documents can be obtained from the following source:

• Partner Portal of Unify

Software Delivery / Deployment

The OpenScape Business TAPI 170 software is supplied on a separate data medium. It is not part of the OpenScape Business System software. The software package can also be downloaded free of charge from the Software Download Server (SWS) within the Partner Portal of Unify.

Licensing

The use of OpenScape Business TAPI 170 is licensed on a subscriber basis. The licenses are managed within the OpenScape Business system. When using the "MULAP" feature, a TAPI license is required for each station within the MULAP.

SW Upgrade / Migration

Before migrating from HiPath 3000 with HiPath TAPI 170 V2 to OpenScape Business V1 with TAPI 170 ensure that a OpenScape Business TAPI License is available within OpenScape Business for every TAPI 170 user. Existing HiPath TAPI 170 user licenses cannot be used further on within OpenScape Business.
HiPath TAPI 170 SW has to be uninstalled and to be replaced by OpenScape Business TAPI 170 SW on the server PC.

Constraints

Only Microsoft Windows operating systems can be used in conjunction with TAPI 170.
The TAPI server and clients must be managed by the same network domain controller, if remote TAPI function is used.

The following applies to the terminal server environment:

• OpenScape Business TAPI 170 must be installed on the same server hardware as the terminal server.
• When using a terminal server cluster architecture, the TAPI 170 software must be installed on each terminal server in the cluster.
• The maximum possible number of OpenScape Business TAPI 170 servers in conjunction with OpenScape Business must not be exceeded. The maximum number of possible connections is reduced if the CSTA links of OpenScape Business are used by other CSTA applications.
