PHP Web Application for Subscription Based Service 'form@ctivate'

In order to develop the application as envisaged by client, we have used Zend MVC framework, JQuery and HTML 5. Twilio telephony API. Further, Braintree payment gateway was used in the project. Users can subscribe to fortnightly, monthly or quarterly subscriptions. Users can also degrade or upgrade subscription any time. We have added functionality so that admin can view subscription payment and revenue generation details. Further, admin as well as users can view call related records too.
