(Assuming this is a school project) don't ask us to do all your work for you. We won't. You have to show that you have put some effort into it by showing us what you have so far.

This is your project, not ours.

have a look at MT8808 IC from Zarlink (formerly MITEL) it is a cross-point switch, ideal for making a small analog PBX (up to 8 lines).

You will need a microcontroller to control that chip and also a line interface circuit for each phone line connected.

I would base this on open-source software as well, have you looked into Asterisk http://www.asterisk.org/

I really have to say, it is amazing!

Best of luck,
