Mike got a couple of "Digium Quad Tdm400P" PCI Phone Cards from a friend so we decided to use a spare computer that was in our apartment and turn it into a PBX.
Were running Trixobx to manage the PBX, and all of the configuration is done through a webGUI.
All of the phones can call each other. If a message is left on a persons voicemail it will be forwarded to their email. Each phone can also order a wake up call!
