I do not know of anybody alive but does not get frustrated when they are having a conversation on the phone and the call gets dropped. A customer of Cavalier telephone can rest assured that this company has all of the necessary precautions in place to prevent any type of interrupted the service. Even if one of the cables on their fiber-optic network gets cut in half the phone call will automatically reroute through another available line instantly. I do not know of any other telephone service that has this quality of technology in place to make sure that there customers are always satisfied with the service.
