SUMMARY
TAPI Service Providers (TSPs) must have a version resource to be displayed in the 'Add Driver' dialog in the Telephony Control Panel Applet (CPL).

MORE INFORMATION
The Telephony CPL reads the first version resource from all TSPs in the Windows System directory to get the strings displayed in the Add Driver dialog box. If any particular TSP doesn't include the necessary version resource, it isn't included as an installable Telephony Driver. The ATSP sample demonstrates how to include the version resource.

This is only an issue with the TAPI 1.0 redistributable telephon.cpl for Windows 3.1. Under Windows 95 and Windows NT 4.0, the Telephony CPL uses the filename of the TSP if the TSP doesn't include a version resource. However, Microsoft recommends that a version resource still be included so that the user can use a friendly name rather than the filename when installing the TSP.
