Handlers and VoiceXML Tools

Handlers process incoming calls and decide whether a call goes through a VoiceXML application. If a handler decides an incoming call must go through a VoiceXML application, it initiates a tool that transfers the call to the VoiceXML subsystem. At this point, a VoiceXML session is then activated and the session activation tool specifies the URL of the VoiceXML document and which dialog to start. The VoiceXML Interpreter then attempts to load and parse the document, and if it is successful, the Interpreter takes ownership of the call.

A handler activates a VoiceXML session using one of the four tools available from the Interaction Designer Tools palette. This palette is on the VoiceXML page.

For more information about the VoiceXML tools, see the following:
