  • Patent number: 6400818
    Abstract: A method of routing interLATA network traffic includes the steps of receiving a number of dialed digits at a first service switching point (18) in a first virtual network (10). Then a query is sent to a service control point (24). When the dialed digits result in the call to a facility (32) in a second virtual network (26) connected to the first virtual network (10) by a tie line (38), the call is routed to a hub service switching point (34) in the second virtual network (26) over the tie line (38).
