Abstract
A system for device registration replication in a packet-based network includes a first call manager and a second call manager that are coupled to the packet-based network. The first and second call managers each control one or more devices and store composite registration information associated with the devices. The first call manager communicates status information to the second call manager in response to a change in the control status of a device controlled by the first call manager. The second call manager updates the composite registration information stored by the second call manager in response to receiving status information from the first call manager.
