If your phones are SIP phones or can support SIP, I suggest you to try
miniSipServer or Trixbox.

miniSipServer is a SIP server for windows, very easy to use and you
can almost deploy your VOIP network in 1 minute with it.

Trixbox is a PBX for linux, it is powerful but complex. If you are
good at linux, it is a good choice.
