If you’ve ever wanted more control over incoming phone calls at home or at the office, setting up a PBX system could be the solution, and Geek.com’s John Rogers has a tutorial for you. He explains what a PBX is:
A PBX or “Private Branch Exchange” is like a miniature phone company/switch in your own office/house. The PBX is responsible for making sure calls are routed properly. Situation: when Joe wants to dial Suzy in the office down the hall or downstairs in the TV room, he just picks up the phone in his room/office and dials a local extension just a few digits long. [...] Also, if Joe has four teenaged kids, instead of answering their calls and acting as the house receptionist, he can just set up a menu that allows callers to dial the person they want and then needs not be disturbed.
