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).
