JTAPI was developed by a group of computer and telecommunications companies (Intel, Lucent, Nortel Networks, Novell, and Sun Microsystems) in 1996. It is a cross-platform multivendor computer telephony solution based on Java. JTAPI uses highly efficient applets, which are small sets of application programming code, for network-based CT operations.
JTAPI added Internet/Intranet functionality to CT, which enables the creation of Web-based applications that integrate with browser applications with call center functionality.
Telephony/telecom programming is essentially the practice of programming telephone services and integrating telecom devices with a computer. It is also known as Computer Telephony Integration (CTI)
