What is VoiceXML over HTTP?
Communication between the Cisco Unified CVP VXML Server and the Voice Browser is based on
request-response cycles using VXML over HTTP. VXML documents are linked together by using the
Uniform Resource Identifiers (URI), a standardized technology to reference resources within a network.
User input is carried out by web forms similar to HTML. Therefore, forms contain input fields that are
edited by the user and sent back to a server.

Resources for the Voice Browser are located on the Unified CVP VXML Server. These resources are
VXML files, digital audio, instructions for speech recognition (Grammars) and scripts. Every
Communication process between the VXML browser and Voice Application has to be initiated by the
VXML browser as a request to the Unified CVP VXML Server. For this purpose, VXML files contain
Grammars which specify expected words and phrases. A Link contains the URL that refers to the Voice
application. The browser connects to that URL as soon as it recovers a match between spoken input and
one of the Grammars.

When gauging Unified CVP VXML Server performance, consider the following key aspects:
•
QoS and network bandwidth between the Web application server and the voice gateway
