Install TAPI driver

If you want to use the CTI Server on a telephone system with a central TAPI driver, the installation of the TAPI driver must be carried out in accordance with the manufacturer's instructions. If the driver doesn't work after the installation immediately, the computer has to be re-booted. You modify the TAPI driver settings still later under: [Start > Control Panel > Phone and Modem Options > Advanced]. In this dialog, select the TAPI driver and then click [Configure ...].
