pre_install.php
This script is called during installation of the YAAI module. The tasks performed during
installation are:
• creation of table asterisk_log in database
• installation of AsteriskJS.php as an „after_ui_frame“ hook in SugarCRM.
This causes AsteriskJS.php (and in turn, dialin.js resp dialout.js) to be included on all pages
rendered by SugarCRM's GUI.

AsteriskJS.php
This script is installed as „logic hook“ and provides the magic® to enhance all pages in the GUIwith YAAI's functionality. Depending on users settings, it conditionally includes dialin.js and/or
dialout.js.
dialin.js
This script is responsible for monitoring calls. When included, it uses AJAX calls (Whoa! Did I already mention we use AJAX?) to callListener.php (which in turn peeks into asterisk_log) to poll (and display) the current state of Asterisk's call activity. Note this script is responsible for both
incoming and outgoing calls.

dialout.js
This script – when included – uses jQuery to dynamically modify the delivered HTML pages to
include an dialout button for phone number fields. callCreate.php is invoked to eventually make a call.

callListener.php
This is the AJAX listener for dialin.js/dialout.js. It retrieves the current call state from YAAI's table
asterisk_log and returns the result as JSON encoded data.

callCreate.php
This script is invoked to initiate an outgoing call. It simply opens a socket connection to Asterisk Manager and sends an „Originate“ action to place an outgoing call.
