Show Notes:

• Ben Klang Principal/Technology Strategist at Mojo Lingo, Project Lead for Adhearsion.


• Ben Langfeld developer at Mojo Lingo, member of Adhearsion core team.


• Adhearsion is an open source voice application framework.


• Rails developers will find some familiarity in Adhearsion’s controllers and routers.


• Adhearsion just released version 2.0.


• New in 2.0, Adhearsion supports multiple backends including Asterisk, PRISM, Tropo, and others.


• Tropo underwrites the development of Adhearsion and also provides features not available on Asterisk, such as high quality text-to-speech.


• IVR stands for Interactive Voice Response.


• Adhearsion plugins are simply gems that extend the Adhearsion DSL and are similar to Rails’ Railties.


• XMPP support has been extracted into a plugin.


• Adhearsion models voice applications as MVC.


• Planning is starting for the next Adhearsion Conf. Follow @AdhearsionConf for details.


• You can watch the AdhearsionConf videos.


• These well done videos were done by our friends Opus Video. We love their split screen presentation. Never miss the speaker or the slides.


• Video is still the frontier for telephony apps.


• Ben Langfeld loves XMPP and helps maintain the Blather library, written by Jeff Smick.


• XMPP pub-sub is hot right now, as employed by the likes of Superfeedr, the subject of Episdode 0.3.7.


• Punchblock “is a middleware library for telephony applications. Like Rack is to Rails and Sinatra, Punchblock provides a consistent API on top of several underlying third-party call control protocols.”


• Adhearsion uses Celluloid which makes Ruby “look and smell a bit like Erlang, but without the yuckiness.”


• Mike Perham, Tony Arcieri, and Charles Nutter inspire Ben and Ben.
