A routing switch made according to the invention is controlled by a Telephone Service Provider ("TSP"). Voice telephone calls of a subscriber with the new service are routed through the routing switch. To establish a telephone connection, the routing switch conferences two voice data paths, one of which leads to the subscriber. The routing switch further monitors the other incoming path, to detect whether a fax incoming tone appears. If it does, it unconferences the paths, and redirects the subsequent incoming fax signals to a fax receive utility. A fax is generated from the fax signals, for sending to the subscriber in a different way, e.g. as email attachment to a prearranged email address of the subscriber.
