Abstract:
1. A scalable call processing node for receiving SS7 messages and for formulating media-gateway-compatible messages, the scalable node comprising: (a) a plurality of link interface modules (LIMs) for receiving SS7 messages over SS7 signaling links and performing call server selection based on first message parameters in the SS7 messages, the link interface modules being capable of processing SS7 messages for at least about n calls per second, n being an integer; (b) a plurality of call server modules operatively associated with the link interface modules for receiving the SS7 messages from the link interface modules based on the call server selection and for performing call setup operations for setting up connections in media gateways, the call server modules being capable of setting up at least about m calls per second, m being an integer, wherein n is variable relative to m by changing the relative numbers of link interface and call server modules; and (c) a plurality of transporter modules operatively associated with the call server modules for formulating media-gateway-compatible messages based on the call setup operations, and for forwarding the media-gateway-compatible messages to media gateways.
