A method of routing interLATA network traffic includes the steps of receiving a number of dialed digits at a first service switching point () in a first virtual network (). Then a query is sent to a service control point (). When the dialed digits result in the call to a facility () in a second virtual network () connected to the first virtual network () by a tie line (), the call is routed to a hub service switching point () in the second virtual network () over the tie line ().

A method of routing interLATA network traffic includes the steps of receiving a number of dialed digits at a first service switching point ( ) in a first virtual network ( ). Then a query is sent to a service control point ( ). When the dialed digits result in the call to a facility ( ) in a second virtual network ( ) connected to the first virtual network ( ) by a tie line ( ), the call is routed to a hub service switching point ( ) in the second virtual network ( ) over the tie line ( ).

Method of routing interlata network traffic

A method of aggregating calls includes receiving a group of dialed digits at a service switching point (52). The service switching point (52) determines if an access code is present. When the access code is present, the service switching (52) transmits an information analyzed query (54) to a switching control point (56). The service switching point (52) then receives an analyze route message (60) from the switching control point (56). The service switching point (52) then routes a call to a hub service switching point (58).
