Part I: Developing Inbound Applications - Time-of-Day Service

The simplest application for Voicent Gateway is a single vxml (VoiceXML file extension) file and a configuration file. Our first version of the time-of-day service just informs the caller the service name.

1. Create Application Directory Structure

First create a new project directory (will be referred to as <tddir>) in your file system. Under the project directory create two sub-directories: conf and webapps.

2. Create Application vxml File

Create a file named timeofday.vxml under <tddir>/webapps and type-in or copy-paste the following to the file:

<?xml version="1.0"?>
<vxml version="1.0">

<form id="td">
  <block>
    Hello, this is Time of Day service.
  </block>
</form>

</vxml>

The format of the file is VoiceXML.

3. Create Application Configuration File

A configuration file is needed to install your application to the gateway. This configuration file specifies the start and exit vxml files, the application type (inbound or outbound), and choice of password protection, etc.

Create a file named timeofday.conf under <tddir>/conf and copy the following information to the file.

name = Time of Day
keyword = Time of day
inbound = 1
outbound= 0
appurl = /td/timeofday.vxml
webappname=/td

4. Check Your Directory Structure

Now you should have a directory structure like this:

<tddir>
  + conf
      timeofday.conf
  + webapps
      timeofday.vxml

What we created so far is a minimum application, a "Hello World" application for Voicent Gateway.
