The traditional phone system has been around for decades, but it is not without its flaws. The box that lives in your office can be high-risk if disaster strikes the area.

Traditional phone systems have what’s called a ‘hub’. The hub is basically the hardware that is located on-premises that connects via wires to each individual phone. The hub is very much tied to the location it is installed at, mobility is rather restricted.
