Introduction to SIP IP Telephony Systems - Technology Basics- Services- Economics- and Installation

1 stars (Little useful information) - This book tries to dumb-down SIP. It looks like it wants to be a training manual for a "Learning SIP" course, but doesn't provide any real technical detail. It is poorly written and a tedious read. This is the first sentance: "SIP is a standardized technology that allows for the sending of voice, data, and video between communication devices on public (e.g. Internet) or private (e.p. local area networks) data networks." ... and it doesn't get any better after that. SIP Demystified by Gonazlo Camarillo is a much better read. It is engaging and well written, providing useful information for IT engineers, managers and technologists. ...

I am lookinf forward the full version if there gonna any... 3 stars (Good High-Level Overview for Beginners) - This is a good, but not terribly polished, high-level overview of telecom billing processes. If you've spent any time at all with telecom billing systems you'll be familiar with 95% of the information in this document, if not more. The material is appropriate for anyone who's getting involved with telecom billing for the first time or who has been working on the periphery of the billing systems and would like to know more. Don't expect a lot of detail - there can't be a lot in a document that contains only 31 pages of content written using large type and a lot of white space. For example, the entire section on Hardware and Software consists of the following paragraph: "The hardware usually includes high performance computers that operate proprietary software. Due to the complexity of hardware and software billing systems, continuous training is required in order to ensure quality services to the customers and to provide revenue assurance." 4 stars (Introduction to Telecom Billing) - This is a good book for anyone who needs a quick and succint introduction on the billing process in Telecom industry without getting into technical details.
