Abstract
A communication network comprising a first node and a second node, the first node configured to transfer a first control message for a call having an inbound call path and an outbound call path wherein the first control message indicates a release request and a carrier, the second node configured to receive and process the first control message to determine if the second node is associated with the first node. If the second node is associated with first node, the second node processes the first control message to determine if the second node has two legs of the inbound call path. The second node transfers a second control message to a third node downstream in the outbound call path if the second node has two legs of the inbound call path. The second node transfers the second control message to a fourth node upstream in the inbound call path if the second node is not associated with the carrier.
