ABSTRACT:
A method and apparatus of communication processing at a client (e.g., media gateway) connected to a server (e.g., media gateway controller) includes collecting events in a quarantine buffer. The contents of the buffer are examined to determine whether the collected events include one or more synchronizing events. An instruction signal sent to the client from the server includes information defining one or more events as a synchronizing event. If one or more synchronizing events is present, the collected events are processed from the buffer relative to the one or more synchronizing events. The processing may include processing the collected events beginning after the most recent or second most recent synchronizing event. The collected events that occurred up to the most recent or second most recent synchronizing event may be moved to a synchronized event list. The synchronized event list may be reported to the server or discarded.
