Assisted Telephony API Reference (Compact 2013)
3/26/2014
Applications use the prototypes defined in the Astdtapi.h file to make telephone calls without requiring the full Telephony API. Assisted telephony and the full Telephony API are used and implemented in different ways; therefore, do not mix assisted and full Telephony API function calls within a single application.
The Telephony API is copyrighted by Intel and Microsoft. You are granted a royalty-free worldwide, unlimited license to make copies, and use the API Service Provider Interface (SPI) for making applications and drivers that interface with the specification, provided that this paragraph and the Intel and Microsoft copyright statement are maintained as-is in the text and source code files.
This feature is added to the OS by default because it is included in the Cellcore.dll. You do not need an extra sysgen; Cellular Radio (CellCore) Catalog Items and Sysgen Variables adds it.
