Description

Telephony development consultant Spencer Roberts introduces the JTAPI architecture, showing how JTAPI cooperating classes and core packages can serve as call models for building virtually any telephony application. You'll review JTAPI's object model, modular components, and class hierarchy - and discover how these can be used to construct advanced telephony applications with carrier-class reliability.

Review quote

Essential JTAPI by Spencer Roberts received a great review by a Java Developers Journal columnist. Below are a couple of excerpts from the review: The Only Serious Book on the Java Telephony API Essential JTAPI travels through the major concepts in the first fewchapters, providing a technology overview and a look at telephony busarchitectures. Having explored telcom programming concepts, the authoranalyzes Javas suitability for addressing industry challenges. He examinescompeting technologies and does a good job of remaining unbiased,presenting the Java APIs as one among many approaches to be applied in thefield. Essential JTAPI ... will tend to appeal to developers in the telephony industry who want to implement either provider solutions or applications that rely heavily on telephony technology. The material is objective, effectively comparing Java with other choices, looking at the challenges that go with JTAPI implementations and providing a good look at what you need to do to get this all working for you. All in all, a targeted book with a lot to offer those who need to address this technology. - Review by Claude Duguay, who manages a software development team at Atrieva Corp. andwrites a column for the Java Developers Journal.
