This book is intended to present some important theoretical and experimental result that I have faced during setting up a VOIP (Voice over internet protocol) server with the well known open source VOIP server Asterisk@Home. To get a brief overview about this book consider the main points of following chapters: Chapter 1 "Introduction of Voice Over IP Home Gateway" which gives a brief overview of this technology and project objective. Chapter 2 "VOIP Overview" covers the hardware, software, network and protocol requirements to setup IPPBX. Chapter 3 "VOIP Signaling Protocol H.323" focused on VOIP signaling protocol that widely use for this service. Chapter 4 "VOIP Signaling Protocol SIP" which is another signaling protocol developed by IETF. Chapter 5 "IPPBX configuration, Part1", which gives a total guideline to setup and configure IPPBX Gnugk. Chapter 6 "IPPBX configuration, Part2", which gives a total guideline to setup and configure IPPBX by Asterisk@Home. i
