Telephony and Conferencing

IP telephony support is also installed during Windows 2000 Professional Setup, including the TAPI 3.0 programming interface and all telephony and media service providers. During installation, Windows 2000 Professional automatically detects, installs, and configures most Plug and Play–compliant modems, adapter cards, and other telephony devices. For devices that are not automatically configured, use the Add/Remove Hardware Wizard to install and configure legacy and Plug and Play devices that require installation information, such as the driver location. Support for telephony devices added after initial Windows 2000 Professional installation can also be provided in this manner.

For a list of supported telecommunications devices, see the Hardware Compatibility List link on the Web Resources page at https://windows.microsoft.com/windows2000/reskit/webresources .

If Windows 2000 Professional is installed over a previous version of Windows that included telephony services (such as Windows 95, Windows 98, or Windows NT 4.0), any previous versions of the TAPI programming interface are automatically upgraded to TAPI 3.0. TAPI 3.0 provides backward compatibility for TAPI 1.4 and TAPI 2.1. If provided in Windows 2000 Professional, device drivers for telecommunications hardware are also upgraded during this migration.
