Abstract
A new destination number determination switching system is provided for a telecommunications environment in which a called party has discontinued an old called party destination number and obtained a new called party destination number. The new destination number determination switching system is used to obtain the new called party destination number when a calling party places a call to the old called party destination number. The switching system includes a hub switch that receives a rerouted call from a corresponding original destination switch. The hub switch corresponds to a routing number prefix used to reroute calls from the corresponding original destination switch to the hub switch. The routing number prefix causes the hub switch to initiate a trigger to a network platform that obtains the new called party destination number.
