TAPI driver for Octophone 86


Call Bridge

For use with Windows 7/8 / 8.1 / 10 64-Bit, the software version of the system must be relatively up-to-date to use the CallBridge V2 R3.15.0 : (2000er, 4000er series and F900 = min. V. 2/3000 series and F200-F650 min. V. 7). If your system has an older software version and you are using Windows 7 64-Bit, you can install CallBridge V2 R2.2.0. The constellation is not officially released, but works in 99% cases. For use with Windows 8 / 8.1 / 10 64-Bit you may have to update your system!

Use the CallBridge V2 R2.2.0 only for Windows 7 64-bit systems, if the system does not have a current software version.

connection diagram

We generally recommend connecting the phone directly to the PC. The following diagrams show the connections schematically: The PABX (eg HiPath) is the gateway to the public telephone network. The phones are also connected to the PC via V.24 (serial COMPort), USB or LAN. Communication between the phone and PC takes place via the CallBridge TA, TU or IP. Setup automatically selects which version of the CallBridge is required during installation. The CallBridge then provides the system with the TAPI (Telephony Application Programming Interface), with which TAPICall can then control the phone and evaluate information about the caller, such as reverse search, answering a call, starting a call, ending a call, timing, speed dialing and more.
