ABSTRACT:
A system and method for efficient routing of communication paths in a telecommunications system. The system comprises a telecommunications network having a pivot node, a destination node, and a release node connected to the pivot node and having a possible connection to the destination node. The method includes attempting to establish a direct connection between the destination node and the pivot node. An attempt is initially made to establish a direct connection between the destination node and the pivot node. If the destination node and the pivot node can be connected directly, then the connection between the pivot node and the release node is released. If the attempt to directly connect the destination node and the pivot node fails, a direct connection is established between the destination node and the release node. The failure to connect the destination node and the pivot node can be indicated by two methods. In the pivot method, the pivot node sends a failure indication to the release node. In the destination method, a timer is started in the release node when the connection attempt begins; the expiration of the timer indicates failure.
