This project was undertaken during the Fall 2012 semester in the DataComm CSCS2700 class.

The objective of this project was to setup an asterisk server and connect devices through it on a local network.

A machine with Asterisk installed on it.

Basically this will serve as a communication server. Phones will be able to use this asterisk server to communicate with other devices that are connected to the server. By doing this it is possible to call somebody on the local network by dialing just '106'.

Once you have asterisk working on a machine (this can be done by downloading the asterisk Cent distro from their website, or by building from source), you need to edit some files to configure everything.
One of these files will be the 'sip.conf' file.
Then there is the 'extensions.conf' file.
Once these files are configured, you will have to use their settings to attach the end devices to the server as well.
To edit the .conf files, you need to follow the asterisk language.
Googling examples makes it very easy to know how the syntax is exactly.

To learn the language for the .conf files I used the examples at: http://jaysonbroughton.com/2011/01/asterisk-and-google-voice-integration/
