Open Feedback Publishing System (OFPS)

While we were writing this book, O’Reilly introduced its Open Feedback Publishing

System (OFPS), which allowed our book to appear on the Web as we were writing it.

Community members were able to submit feedback and comments, which was of

enormous help to us. The following is a list of their names or handles

Thanks to all of you for your valuable contribution to this book.

Thanks to Sean Bright, Ed Guy, Simon Ditner, and Paul Belanger for assisting us with

clarifying best practices for user and group policies for Asterisk installation. In the past

it was common to just install Asterisk with root permissions, but we have elected to

describe an installation process that is more in keeping with Linux best practices,

and

these fine gents contributed to our discussions on that.

Kudos to all the folks working on the FreeSWITCH, YATE, SER, Kamailio, OpenSIPS,

SER, sipXecs, Woomera, and any other open source telecom projects, for stimulating

new thoughts, and for pushing the envelope.

Everyone in the Asterisk community also needs to thank Jim Dixon for creating the

first open source telephony hardware interfaces, starting the revolution, and giving his

creations to the community at large.

* We tried wherever possible to include the contributors’ names, but in some cases could not, and therefore

included their handles instead.

† Without starting a holy war!
