VoIP at home

Have you ever wondered how to turn your home landline telephone into a professional VoIP service circulating into different rooms all over your house?

It's pretty simple:


With a simple PBX box, you can run your own asterisk at home setup. You just need to simply install Asterisk in your Linux machine and have your analog card installed and your good to go. In this illustration, the FXS modules (green modules) connect to the analog phones. They have a 1:1 Ratio, 1 FXS module per 1 analog device (RJ11 phones and fax machines). The FXO module connect to the telco line, which the line coming from the wall socket of your telephone service provider. All modules are connected to a base board (like a motherboard for modules). In this illustration, we have Zapmicro's ZMA400P base card.

You can configure extensions and local numbers from within your own Asterisk home network and call each other up without affecting the outside line.

If you'd like to see more Asterisk hardware that are priced lesser than Digium's, check out PBXEQ.com.
