The web server

 
The web server is a physical, customer-provided server where GVP applications reside. A standard Web Server such as:

• Microsoft Internet Information Server 5.0 or 6.0 depending on which version of Windows Server.
• Jakarta Tomcat on Windows

• Apache on Windows/Unix (if stand alone web server) must be added to the GVP deployment architecture .

Requests and information exchange on the VCP/IPCS are handled in a similar way as normal html requests, but the markup language is VoiceXML. The IPCS or VCS, which contains the VoiceXML browser, parses the VoiceXML and executes call handling (answering, bridging, disconnecting calls), media management (play greetings, prompts, and messages using cached voice files and text-to-speech), and user input (collect touchtone digits, contact speech recognition engines).

VoiceXML enables a web voice application to drive an interaction with a caller in the same way that it would interact with a desktop web browser to render a screen and react to keyboard or mouse input. As with the desktop browser, any changes to the application software at the web server become effective the next time a page is requested.
