This document provides an overview of a VoIP Drupal hands-on experience. It discusses enabling required VoIP Drupal modules, configuring server and call settings, selecting scripts and languages, editing sample scripts using Visual VoIP Drupal, and calling into a conference call. Potential applications of the VoIP Drupal platform are outlined. Key benefits for administrators and developers are highlighted. Upcoming VoIP-related events at DrupalCon Denver are also listed.

In addition to VoIP Drupal's required modules, some examples in this
Webinar use two more. Please install them in order to follow along with
me.
They are not required, but will be necessary to follow all examples in this Webinar.

7. What about those
README.TXT files?

8. README.TXT – voipdrupal core module
VoIP Drupal is an innovative framework that enables users to contribute and access
Drupal content via regular touchtone phones, SMS and a variety of Internet-based
communication systems such as Skype, IM, or Twitter.
In technical terms, the goal of VoIP Drupal is to provide a common API and scripting
system that interoperate with popular Internet-telephony servers (Asterisk, FreeSwitch,
Tropo, Twilio, etc) dramatically reducing the learning and development costs associated
with the construction of communication systems that combine voice and text technologies
together.
This project is under continuous development. Discussions are taking place on the VoIP
Drupal Group (http://groups.drupal.org/voip-drupal).
Please check the VoIP Drupal Handbook for additional information (http://drupal.org/node/
1078710).
The VoIP Drupal platform has originally been conceived and implemented by the MIT
Center for Future Civic Media (http://civic.mit.edu/).

9. Hello world
$script = new VoipScript('hello_world');
$script->addSay('hello world');
$script->addHangup();

10. Office Hotline
$script = new VoipScript('voipscript_small_office_ivr');
$script->addSay(t('Welcome to our office hotline.’));
$script->addLabel(‘office_menu’);
$options_menu = t(‘For sales, dial 1. For customer support, dial 2. For hours of operation, dial 3. To hang up, dial the star key.’)
$input_options = array(
‘1’ => ‘sales’,
‘2’ => ‘customer support’,
‘3’ => ‘hours’,
‘*’ => ‘hang up’,
‘I’ => ‘hang up’,
‘t’ => ‘hang up’
);
$invalid_msg = t(‘Invalid option selected.’);
$script->addRunIvrMenu($options_menu, $input_options, $invalid_msg);
$script->addGoto(‘%ivr_option_selected’);
$script->addLabel(‘sales’);
$script->addSay(‘Sales department’);
$script->addGoto(‘hang up’);
$script->addLabel(‘customer support’);
$script->addSay(t(‘Customer support department’));
$script->addGoto(‘hang up’);
$script->addLabel(‘hours’);
$script->addSay(t(‘Our office is open Monday to Friday from 9am to 5pm.’));
$script->addGoto(‘office_menu’);
$script->addLabel(‘hang up’);
$script->addSay(t(‘Thanks so much for calling our office. Bye bye.'));
$script->addHangup();

12. How things work

13. SCREEN SHARING >>>>> Set up Tropo Application Setup
Then back to Drupal site to configure

14. SCREEN SHARING >>>>> show enabled modules and talk about their
virtues:)
SCREEN SHARING >>>>> Server and Default Call configurations

15. Location of VoIP Drupal Scripts
There are several script examples that are included in the
voipdrupal downloaded module. You can *view the scripts in a list
by going to this URL within your Drupal site:
http://your_site.com/voip/voipscripts
Today we will be looking at the Conference Call script:
/voip/voipscripts/view/voipscript_join_conference
* To see the sample scripts, you will need to have the Views module installed
and enabled - http://drupal.org/project/views

16. SCREEN SHARING >>>>> Enable the default Call Inbound script.

Tropo and hear the default welcome message
Select the Conference Call Script
