System and method for managing a plurality of calls

摘要

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