Section 470 - TSAPI Programmer's Guide
Notes:
The DBS requires the driver to specify not only which extension's message waiting indicator
to activate, but also the extension number (e.g., voice mail) that is activating the indicator. In
future releases, applications will inform the driver of the activator's id in private data;
however in Release 1.0 the extension value must be specified when the driver is loaded or
during runtime using the driver's command line switches and/or runtime menus.
