How to turn your computer into a communications server with Asterisk (VoIP server at home).

What is Asterisk?

Asterisk is a complete PBX in software. Works on VoIP protocols, and doesn’t need any external hardware to work. More information on their Web.

What we will do?

We will only configure the server to on the network via IP protocol. You can use with a simple configuration in your intranet or you can buy a subscriber telephone line through one company and get your external number, and use the server to make international calls. More info.
There are many options to install and configure Asterisk on your computer, like downloading ISO with pre-configured software(AsteriskNOW), download versions of the software with some modifications, etc. But we will create our own server from 0 using the Asterisk from Ubuntu repositories installing in Ubuntu 12.10.
