node as adapted to connect the second and first telephone stations. The method
includes the following steps: at the service switching point forwarding a request
to the service control point to identify one of the plurality of service nodes
to handle an automated call back from the second station to the first station;
searching the database at the service control point for one of the plurality of
service nodes to handle the automated call back to the first station from the second
station; identifying to the service switching point, one of the plurality of service
nodes to handle the automated call back from the second station to the first station;
forwarding to the service node a request for automated call back from the second
station to the first station; and upon receiving a signal from the second station
at the service node, connecting the second station and the first station.
