Windows Telephony Programming: A Developer's Guide to TAPI offers C++ programmers a clear and concise tutorial to Windows Telephony that significantly reduces TAPI's steep learning curve. TAPI is an API that has standardized the interface between computers and telephony hardware. Included with Windows 9x and Windows NT, TAPI is a major element of the Windows communications backbone. Despite its growing importance, TAPI may still be very daunting and difficult to master. The author makes TAPI more accessible by revealing its underlying architecture and rationale and by relating its functions and features to specific tasks developers seek to accomplish in their applications such as making, answering, and monitoring calls, handling modem data, and building an answering machine. In addition to carefully developed, intuitive explanations, Windows Telephony Programming features numerous real-world examples of how actual TAPI programs are built, and a comprehensive C++ class library that takes much of the "grunt" work out of TAPI programming. The author also discusses building a telephony service provider and includes a complete working example.
Completely up-to-date, this book covers TAPI versions 1.x to 2.0, and offers a glimpse into the future of telephony with a preview of the new TAPI 3.0 incorporated into Windows NT 5.0. To exploit the power of TAPI 3.0 when it becomes available, it is imperative that you understand TAPI 1.x and 2.0 first. This book provides the clear methodology to gain that understanding. 0201634503B04062001
