In the past, when you call an office building or business, you would either be transferred to the department you want to talk to, or given their extension number. This extension is usually a 2-3 digit code that when dialed, transfers you automatically to the particular person or department you want to speak with. The reason why this code works is because it is programmed into a PBX system.
The Home Phone system is the solution to saying goodbye to your traditional phone company and to immediately start saving money. Seriously! You can literally save hundreds of dollars every year by using the Home Phone system.
