We have a Toshiba DK424 and I am interested in adding a IP extension. I currently have our office connected to my home via a VPN tunnel. I would like to have an extension at my house.

Unfortunately, I like to think that I am computer/network savvy but never have tinkered with a Toshiba PBX, which I hear is very tricky. I would like to try to attempt to tackle this though.

Is this possible to do without having to install Toshiba's "CallManager" type software which I do not have. Could someone give me price ranges also? I would like to have the same functionality (extension, intercom paging, etc) from home as I have at the office.

TIA!
