General information about UNIFY / Siemens TAPI120

The HiPath (at Telekom: Octopus) TAPI 120 is software that requires a license. When the system was purchased, 6 usable TAPI120 licenses were acquired. HiPath TAPI120 enables PC-based calls with CTI software from various manufacturers.

If only up to six clients are to be connected, a connection can be established directly via the PBX. To do this, only install TAPI120 without a CMD server on each of the clients. From the seventh client, the CMD server must be installed on a server. The latter can then manage further TAPI120 connections if you have purchased licenses.

Important instructions

If you want to use the HiPath 3000 series with HiPath TAPI120, you have to use this HiPath HG 1500 be integrated. Windows does not support Starter / Home Basic / Home Premium Edition.

If you want to connect an Openscape BUSINESS system, the following must also be observed:

  • Unify currently only supports the rack variant. Unify is working on supporting the wall variant.
  • The "UC Booster Card OCAB L30251-U600-A841" must be installed with the "OpenScape fan kit for OCAB".
  • TAPI120 licenses must be purchased directly from the first client.
  • When installing the client, only "TAPI120" may be selected because the "CMD server" is not required.

HiPath TAPI170

In addition to TAPI120, there is also the TAPI170. In contrast to 120, 170 is only installed on a Windows server. This has many disadvantages: Windows 8 is not supported, ports have to be opened, Microsoft Office is required in 64-bit and disadvantages. We therefore always recommend TAPI120 or 1st Party.

installation instructions

Start the setup file of the TAPI driver and follow the user guidance. The PC restarts during the installation.


line numbers

With the appropriate setting, line numbers 7801 to 7830 are no longer incorrectly reported to the TAPI driver:

HiPath TAPI 120 170 Configure in the telephone and modem options. tg. Code 7801 to 7830 (with thirty lines on the primary multiplex or only 7801 to 7808 on the system connection with four NTBAs) so that the TAPI driver from Siemens HiPath no longer delivers these line numbers to the TAPI interface for anonymous calls.
