Abstract

A system includes a switch responsive to a control module. The control module that determines whether an incoming telephone call from a telephone number to a telephone line is a facsimile call or a voice call and whether facsimile calls are authorized to be routed to the telephone line. When the incoming telephone call is a voice call, the control module instructs a switch to route the incoming telephone call to the telephone line. When the incoming telephone call is a voice call, the control module instructs the switch to route the incoming telephone call to the telephone line when facsimile calls are authorized, and to deny routing the incoming telephone call to the telephone line when facsimile calls are not authorized.
