Abstract
An IP-telephony system including one or more nodes coupled to a session controller. Each node includes a service gateway coupled to one or more terminals. A first terminal conveys a start page request initiating a page activity between itself and one or more terminating terminals. The session controller receives the start page request and in response, conveys first control signals to one or more service gateways, each first control signal containing information identifying which of the terminals associated with a service gateway is a terminating terminal. In response to the first control signal, each service gateway conveys second control signals to its associated terminating terminals. The first terminal conveys a media packet to the first service gateway during a page activity. The first service gateway forwards the media packet to one or more designated terminating terminals.
