The presentation will start with a brief panoramic of Adhearsion 2 and how to connect an app to a voice platform, then moving on to real life use cases. A quick look at the future with WebRTC and browser-based services will then let us find out where technology is heading. Adhearsion is a voice application framework that allows Ruby developers to build complex systems on top of Asterisk, FreeSWITCH and other VoIP platforms, used in the industry for very heterogeneous purposes. Most of it happens behind the scenes and inside calls, through IVR menus and with the notoriously complex CDR output acting as the only trace. The presentation will start with a brief panoramic of Adhearsion 2 and how to connect an app to a voice platform, then moving on to real life use cases such as pushing events to a browser or a queue, robo-dialing with real time status reporting, and authenticating users by phone number or PIN through a Web API. A quick look at the future with WebRTC and browser-based services will then let us find out where technology is heading.
