Abstract
A system (10) includes a calling party (12) that initiates a call to a ported customer (14). Upon receiving the call from calling party (12), switch (16) generates a trigger indicating that ported customer (14) is now being serviced by another switch (20). Switch (16) transfers the call to a service node (22) that includes a database (28) containing routing information. Service node (22) routes the call to switch (20) now providing service to ported customer (14). Several variations of calls to ported customer (14) are described.
