PBX Driver Installation
Telephony Services for NT installs INSTTSDR.DLL, a utility library for PBX driver
installation.
INSTTSDR.DLL exports a function called installTelephonyServicesDriver(). Your PBX
driver's installation routine may call this function in order to add the driver's name to the
Tserver's list of drivers.
The INSTTSDR.H header file specifies the C-language interface to the functions in
INSTTSDR.DLL.
installTelephonyServicesDriver() is a convenience routine so that the user does not have to
manually add the driver to the Tserver's list of administered drivers via TSA.
You may not include INSTTSDR.DLL with your PBX driver; rely on the Telephony Server to
provide this file.
Sample Code
Figure 8-8: Sample Code on page 190 provides sample code for using the
installTelephonyServicesDriver() function with a popular installer, InstallShield3.
