Abstract: Described are methods and apparatus, including computer program products, for using a single point code to represent multiple switching devices. A first software node and a second software node are associated to the single point code. The first software node is assigned to a first switch and the second software node is assigned to a PSTN. Signaling data associated with the point code is received via signaling links associated with the first switch. The signaling data is routed to the first software node or a second switch based on a criterion.

Abstract: Described are methods and apparatus, including computer program products, for active switch replacement using a single point code. Signaling data associated with the point code is received via signaling links associated with the active switch. The signaling data is routed to a replacement switch if the signaling data is associated with voice trunks associated with the replacement switch. The signaling data is routed to the active switch if the signaling data is associated with voice trunks associated with the active switch.
