ABSTRACT:
A control system for processing calls comprising a call handling device and a device controller that are each connected to a network via a call connection interface that permits establishing and releasing a network connection, participation with another call connection interface in the same network connection, and either control over a network connection when the interface is the sole interface participating in that connection or control over a network connection to drop the last leg added to a network connection, the device controller and call handling device sending messages to each other over a message transfer interface. Also disclosed are a system for shifting control of a network connection and a system for monitoring the state of a network connection from a network interface that is not actively engaged in the network connection.
