Linux aims to be fully POSIX compatible, and so a Google search regarding POSIX system calls or a POSIX reference book should cover your question.

You have the ability to make free calls form you PC,Linux,Mac,Mobile and most tablets. Each platform has its own set Apps or services available to the operating system it is on. You have a variety of ways to accomplish FREE calls. Take a moment decide which platform you want to use and see whats available. the quicker you do it the quicker you will probably be on your way to saving some money too on calls.
