This document discusses Adhearsion, an open source framework for building voice applications using Ruby. It provides an overview of Adhearsion's features such as its easy-to-use DSL, powerful eventing system, and plugins. The document also covers Adhearsion's applications in areas like call centers, sales automation, and conferencing. It compares Adhearsion to alternatives like Asterisk and Tropo, and outlines Adhearsion's architecture including its integration with technologies like SQL, LDAP, XMPP, and web services. Finally, it presents a sample problem of organizing a spontaneous conference call and proposes a solution using Adhearsion and other technologies.
