As all of the phones that appeared on our list have multi-line operability, we feel obligated to inform you of the setup process of the multi-line phone system properly. It’s true that you can’t do the whole thing completely by yourself.

But with this guide below, you can surely save some money. You’ll need the help of a technician from your phone company to run a wire from the phone box placed outside of the building to the inside. After that, you’ll need no one else’s help.
