TAPI Registry Settings (Windows CE 5.0)
The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.
To enable multiple Telephony Service Providers (TSPs), the registry values that are specific to a service provider are located in a subkey of the device. When a new device driver is loaded, the device manager looks for a subkey that contains the TSP value and then notifies Telephony API (TAPI). TAPI then loads the service provider and passes a pointer to its specific values.
Note The default registry values vary depending on which Catalog items are included in your OS design. For more information, see Default Registry Settings.
