Meanwhile, a fellow co-op and friend, Adam Schreiber, introduced me to Mark Spencer. Over the next six months, I immersed myself in Asterisk. I learned as much as I could about Asterisk, telephony, and C programming. 0 was released in the fall of 2004, I was named the release maintainer. At the beginning of 2005, I was hired by Digium to continue my work on Asterisk professionally. I have spent the past six amazing years working with Digium to improve Asterisk. I have worked as a software developer, a software team lead, and now as the engineering manager of the Asterisk development team.
Besides, I had been writing a lot of papers at school, so I was getting better at it. One night I put up a website called The Asterisk Documentation Assigned (TADA) and started writing down any documentation I could. org), with the goal of writing an Asterisk book for the community. That project became the basis of the first edition of this book, Asterisk: The Future of Telephony. Nine years later, I’m still writing Asterisk documentation and have become the primary bug marshal and release manager for the Asterisk project, spoken at every single AstriCon since 2004 (at which Jared and I spoke about the Asterisk Documentation Project; I still have the AsteriskDocs magnet his wife made), and become a consultant specializing in database integration (thanks Tilghman for func_odbc) and clustering (thanks Mark Spencer for DUNDi).
