How can i make a home phone system using an old pc and some spare phones and our LAN ?

I have a keen interest in both telephone systems and IT so just more for interest than anything else i would like to make a phone system that would let me make internal calls and external calls using an old pc and existing land-line phones over the lan any info would be greatly appreciated.

take a look at http://www.asterisk.org/ it is a software PBX that you can install on your old PC… you may however need to get some cards to interface with the telephones….

it does everything that a phone system does, so calling internally between phones would be possible… but not only that, you could set up SIP service and be able to call out with it as well…

I have not yet tinkered with it yet, so the fourms on the website should be able to assist you further…
