The big benefits for developers, vendors, and end users will be creation of the kind of personal telephony applications that TAPI and Microsoft Windows enable. Next-generation telephony will help end users get the most from telecommunications systems, allowing them to more efficiently manage their voice calls and control their data-transfer operations. TAPI can bring this efficiency to any application—database manager, spreadsheet, word processor, personal information manager—any application that can benefit by sending and receiving data through the telephone network. This will bring immense benefits to all segments of the CT industry, ranging from software developers and hardware manufacturers, to resellers, telecom managers, and business users.
