Abstract (en)
[origin: WO0115486A1] Events and optional signals are added to the protocol that is used by a media gateway controller (MGC) (301, 302, 401, 402) to control a media gateway (309, 310, 414, 415). These events and signals allow call setup to be monitored by an MGC without actively waiting for call setup, thus avoiding the overhead involved with processing a wait state. The invention can be used to control call processing exclusively, or it can be used in conjunction with transaction pending messages.
