SYSTEM AND METHOD FOR MANAGING A PLURALITY OF CALLS

摘要

A call management system comprises a first node that receives a message announcing a through-connection for a call and records a record of the call in a memory. A second node communicates with the first node for making the through connection for the call.A method of managing by a first node calls maintained by a second node comprises the steps of connecting a first call 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 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.
