System and method for managing a plurality of calls

摘要

A system adapted to manage a plurality of calls, including a first call, comprises a first node including a memory for receiving a message announcing a through-connection for the first call and recording a record of the first call (including an indication of the through-connection) in the memory. The system includes a second node in electronic communication with the first node for making the through connection for the first selected call. A method of using a first node including a memory to manage a plurality of calls maintained by a second node includes the steps of connecting a first call selected from the plurality of calls to provide a first call through-connection at the second node, receiving a message at the first node announcing the first call through-connection, and making a record of the first call (including an indication of the through-connection) in the memory of the first node. Restart operations may be announced to the first node by the second node and calls will be released by the second node according to whether records made of the calls in the first node include an indication of a corresponding through-connection.
