Product description

From the Publisher

While many books describe the theory behind Voice over IP, only this one describes how such a phone system was actually built, and how you too can acquire the source code, install it onto a system, connect phones, and make calls. Because VOCAL is open source, you can look "under the hood" to discover how the system works, and how common problems are being worked out in the development environment
