Adhearsion is an open-source voice application development framework. Adhearsion users write applications atop the framework with Ruby and call into their code.

Adhearsion rests above a lower-level telephony platform, namely Asterisk, and provides a framework for integrating with various resources, such as SQL, LDAP and XMPP (Jabber).

Adhearsion has...

• An elegant dialplan system for writing the code which controls a live phone call
• A sophisticated Asterisk Manager Interface library with a lexer written in Ragel.
• An events subsystem which maintains a Thread-pool for executing your namespaced callbacks. (supports AMI events too!)
• A very useful component architecture with which you may write Adhearsion plugins and share them with the world.
• JRuby compatibility for running atop the Java Virtual Machine and using virtually any Java library.
• Ability to re-use existing Ruby on Rails database models with ActiveRecord/ActiveLDAP
• Easy interactive communication via XMPP instant messages using the Blather library
• Good regression test coverage

Don't want to screw with setting up a telephony system? You can test your Adhearsion applications using our public sandbox!
