Figure 1: Unified CVP Standalone VXML Server - HelloWorld Voice Application Call Flow

The basic steps in the call flow, as shown in the diagram, are:

1. (1A or 1B) The user dials a specific number (called the "dialed number" or DN) using an

analog phone connected to the voice gateway's FXS port connection (or a VoIP phone,
when using the alternate version of this exercise).

2. The voice gateway matches the DN with a "dial peer" which is configured for specific

handling based on the DN. In this case, the handling instructions for the DN are to launch
the HelloWorld application. (HelloWorld is a default application that resides on the Unified
CVP VXML server.)

3. The voice gateway makes an HTTP request (through its voice browser) to the VXML

server to initiate the HelloWorld application.

4. The VXML server instructs the voice gateway to play the HelloWorld.wav file to the

caller.

The following components are used in this exercise:

•

An ingress gateway (part of the voice gateway) which accepts the analog call input, converts
it to digital, and sends HTTP-based information to the CVP application using the voice
browser.

•

The CVP VXML server, which executes the IVR application requested by the voice gateway.

•

A voice browser (part of the voice gateway) which processes the VMXL server responses.
