Adhearsion is an open-source framework written in Ruby that was developed to improve complex Asterisk development. Jay Phillips is the creator of Adhearsion and he has written a section about the open source Ruby framework for the upcoming second edition of Asterisk: The Future of Telephony. We’re proud to present this expanded excerpt of Jay’s material here on ETel. Our latest ETel article explains how to get up and running with Adhearsion, provides working examples, and a detailed discussion of Adhearsion’s database integration. For the all of the latest Asterisk info, the newly updated version of O’Reilly’s best-selling Asterisk book is available now as a Rough Cut.
