After two long years we finally got the Intro to VOIP class on the fall
schedule at PCC. Here's the official description of the class:
CRN 15065 CIS 298T8
Introduction to the concepts of Voice over Internet Protocol (VoIP) from
the history to expected future uses in the workplace and home. Includes
an overview, digital voice fundamentals, standards, how an Internet
Protocol (IP) phone call works, protocols and structure, relationship to
the Open Standards Interconnection (OSI) model, gateways, quality of
service, and router concerns.
While this sounds pretty generic and boring, the class will actually
cover the introduction of telephony technology from the analog (stone)
age to the present.
The first class will be an introduction to telephony and an overview of
where it came from. Then we will get into the exciting stuff like
actually building and programming some telephony servers.
The software used in the class will be Linux, possibly Debian and the
Asterisk open source application software. We will cover how to install
Linux and Asterisk then get into configuring it so you can actually make
some phone calls. We will use some soft clients as well as some hard IP
phones and cover such things as configuring phones from a ftp server to
hardening the system, security, QOS issues, as well as voice mail to
your e-mail box.
We hope to get enough students to have 4 or 5 teams of 4 students each
who will build and configure their server and network them together so
we can place calls to and from each server and possibly to the outside
What good is the class? Well, if you are at all interested in the
digital world, as I assume many Tfugers are, this is how all of your
voice service will work in the near future if it doesn't already.
Digium, the company that developed the open source Asterisk offers a
DCAP or Digium Certified Asterisk Professional certificate. Since we
will be using their recommended book, this is a good way to get up to
speed and possibly get their certification although we don't
specifically offer that as the goal.
It's only a three credit class on Wednesday night at West Campus from
5:40pm-08:30pm. While telephony isn't the most exciting application in
the world, it's one that is ubiquitous in that everyone has some sort of
phone service. ;-)
There are no formal prerequisites although some knowledge of Linux and
networking would be very useful. If you have any questions, contact me
off-line and I will be happy to tell you more.
