• a first switch that receives a call from a calling party to the old called party destination number and determines that the old called party number is discontinued, and that changes a routing number prefix of the old called party destination number to a predetermined rerouting number prefix;
• and
• a second switch that receives the call from the first switch, the second switch associated with the rerouting number prefix, the rerouting number prefix causing the second switch to initiate a trigger to a network platform that obtains a new called party destination number associated with the old called party destination number.
