How

...

it works

Here's how Call Interactive works:

...

We will exemplify how to navigate through an IVR using a Call Interactive request to a simple PHP script. 

Step 1: Configure the Script that you want to call from the IVR. For testing purposes, you can copy copy the following code to a file named test_callinteractive.php that can be accessed over the Web.

<?php
$req_vars = $_GET;

# Here you can add any logic you want in order to decide where to jump
$reply='<?xml version="1.0" encoding="UTF-8"?>
    <Response>
        <Jump context="Welcome" option="0" priority="1">
        </Jump>
    </Response>' ;
if ($req_vars['code']=='1'){
    $reply='<?xml version="1.0" encoding="UTF-8"?>
    <Response>
        <Jump context="Welcome" option="1" priority="1">
        </Jump>
    </Response>' ;
    }
echo $reply
?>

Step 2: Configure the IVR contexts. 
Add  Add the entry context named Welcome.  In In the Start option of the Welcome context, add the following actions:

• Play Sound welcome

• Record 1  digits digits to variable code Stop Stop recording after  9  seconds of inactivity.   Play before starting recording recording ////dictate/record

• Call Interactive Interactive:

• Request Method - GET
• Make request to - must be set to an URL of the following form:

...

•  http://<ip|host>/<PATH_TO_TEST_SCRIPT>/test_callinteractive.php?code=$code

In the 1 option of the Welcome context, add action:  Play Play Sound ////digits/1
In the 0 option of the Welcome context, add action:  Play Play Sound ////digits/0

Step 3:  Generate Generate the IVR.

Step 4: Call the IVR from a phone terminal extension.

When you hear record, press any digit. If you press digit 1, the IVR will jump to context Welcome at option 1. Otherwise, it will jump to the same context at option 1.

Here you can read more about what variables and actions are available through Call Interactive.

and tricks

Don't forget to close all tags in the XML response page. To make sure the XML is OK, it is best to start with a simple XML response, like Hangup, and then modify it to process data.
