A system may install a trunk between a first switch and an end office, where the trunk is a trunk home for the end office. The system may further identify Numeric Numbering exchanges (NXXs) that home to the end office. Traffic for at least one of the identified NXXs is routed to the end office through a second switch that is different than the first switch. The system also causes traffic for the identified NXXs to be routed to the first switch.
