blitzrage writes: The third edition of the Asterisk book published by O'Reilly Media, Inc. is using a new book review system for Asterisk: The Definitive Guide which is being released under a Creative Commons license (the same as the previous two editions). The difference with this edition is the public review process using the Open Feedback Publishing System (OFPS) software which is in its second iteration. While the book is incomplete and the software is beta, you can review and read the book in its entirity while it is being written by the authors and offer feedback on the various sections that have been written.
Thinkcloud writes with a note that long-standing open-source VoiP software Asterisk has just been updated, and it's packed with more than 200 enhancements, security updates, and new features — including calendar integration and support for Google Voice and Google Talk. Asterisk's fully-featured PBX includes call waiting, hold and transfer, caller ID, and other useful tools so it's a great option for small businesses that need to watch costs."

mjgraves writes "Over the past week a number of IP-PBX systems have been suffering SIP attacks from hosts in the Amazon EC2 cloud. At least a dozen known attacks have been reported to Amazon, which has been surprisingly quiet about the matter. The issue has been well documented by one of the attack victims on his blog. The matter was also discussed on the April 16th issue of the VoIP Users Conference (podcast available at the link; EC2 segment begins around 3:30). Amazon appears to have gone silent on the matter even as the attacks are ongoing. This is completely irresponsible behavior from a such a hosting company, which should be acting to take down the attacker in their midst."
