PSC 94 Box 361 APO 09824, Watching Asterisk move from being a personal coding project to a community of.
tens of thousands of programmers and millions of users has been quite the ride. so far Asterisk is only now hitting its prime and there are so many more things. that creative people are going to do with the code The growth of the project over. the years has stunned and pleased me and it s amazing that well written and. comprehensive books like this now exist to help more advanced users navigate the. waters of larger and more complex Asterisk installations Asterisk installations are. now huge both in numbers of locations and the unimaginably large size of many of. those locations thousands or tens of thousands of users Asterisk implementations. are rarely limited by the capability of the software but more often by not knowing. how to utilize it Books like this play an important role in getting the experience of. those who have already done in the hands of those who want to do. Hopefully the knowledge here allows you to continue your adventure with Asterisk. moving from the basics of PBX construction to having the ability to quickly implement. advanced call logic processes and work with the more exotic telephony and VoIP. interfaces The motto of There s more than one way to do it is almost always true. with Asterisk this book seems to contain an excellent cross section of at least one. of those ways to do it whatever it happens to be for your application and you ll. quickly think of many other ways once you ve mastered the methods shown. The authors here have really shown some excellent detailed explanations of how. to use Asterisk and I hope this provides the incentive for you the reader to. experiment in more wide ranging ways with Asterisk once you ve understood the. basics Most of the Asterisk community has learned with hands on experimentation. and it s great to see more encouragement of this type of learning as is contained in. these pages Kudos to the authors especially David Duffett who has been involved. with Asterisk for so long and has taught so many people their first dialplan routines. and hopefully has left them uninjured from his famous habit of throwing candy at. people who give correct answers in class or in his talks.
