Cisco Cisco Customer Voice Portal 8.0(1) Developer's Guide

Page of 122
Introduction
Cisco Unified Customer Voice Portal (Unified CVP) software has been designed to be easy to
use but highly extendable. While the software provides enough to produce high quality voice
applications out of the box, many users will want to extend the functionality of the software by
building custom components that perform very specific tasks. This document describes the
processes and application programming interfaces (APIs) provided for a developer to construct
and deploy these components.
The components a developer uses the APIs to construct are: configurable action, decision, and
voice elements, standard action and decision elements, dynamic element configurations, start
and end of call actions, start and end of application actions, the on error notification, hotevents,
Say It Smart plugins, and global and application loggers.
Requirements
All components require programming effort to construct. In order to build these components,
Unified CVP provides a Java API as well as an API that allows the use of other programming
languages. Therefore, the reader should at least possess a familiarity with programming concepts.
Some components can only be constructed using the Java API and so for these components, the
reader should possess a familiarity with the Java programming language. The reader should
understand Java interfaces and abstract classes, extending classes and overriding methods, static
variables and methods, Java collections, and compiling and deploying Java classes and JAR
files. Unified CVP does not require very complex Java coding, knowing the basics of the Java
language will be sufficient to start working with the Unified CVP Java API. Most of the
information about the Java API is encapsulated in the API’s Javadocs. This document will serve
to provide a starting point and the Javadocs will provide the details.
Some components are used to produce VoiceXML, the language used to communicate with a
voice browser. When building these components, a familiarity with VoiceXML is essential.
The Java API used to produce VoiceXML follows the same design as the VoiceXML language,
