routing processor. The call routing processor receives status information on at
least two call service centers and provides routing instructions to both the interexchange
and local exchange networks. The method includes the steps of a call controller
in a local exchange network communicating with a call routing processor also in
communication with an interexchange network, the call controller identifying calls
to call service centers and requesting instructions from the call routing processor.
