TelecomWorld 101 provides telecommunication professionals and those who are interested in Voice over IP (VoIP) with information on many different platforms including the open
source Asterisk Private Branch Exchange (PBX). TelecomWorld 101 is divided up into sections indicated by the menu buttons at the top of this page. Each button will take you to a separate section that deals with a particular area. This is a new site and I (yes, just one person) am slowly writing the webpages and filling the site. My plan is to cover a lot of areas not normally covered when discussing VoIP to start with.
What the Heck is Telecommunications?
Normally it is all telephony but there is a huge area that covers the OSI model, network side and server side that most telephony gurus don't know about. I've started from the left side with the Reference section and completed the Network section. I'm halfway through the Server pages and I've updated the VoIP section with Asterisk using PBX in a Flash, a FreePBX reference section and configuring Cisco Call Manager Express (Dec 2012)! I expect that it will take a while to complete this site if that is possible! So be patient, sit back, read, learn and enjoy!
The TelecomWorld 101 website is divided into the following sections:
 Reference - This section is a reference source based on the
OSI model. Each layer is discussed including the software and devices associated with each layer! This is a good place to start if you are justing learning

to know about the network specifically pertaining to VoIP and it covers LANs, VLANs, WANs, traffic patterns, Subnetting, QoS, etc..
