Abstract:
1. A media gateway comprising: a receiver module, said receiver module of said media gateway in communication with a packet-based network and a publicly-switched telephone network, configured to receive or transmit data associated with a plurality of calls from one or more signaling links, the data including content information and signaling information, the signaling information being Signaling System 7 signaling information; a first processor module, said first processor module of said media gateway in communication with the receiver module, the first processor module being coupled to the packet-based network an active communication link and being configured to: i) received data associated with the plurality of calls from the receiver, ii) determine and maintain state information about the one or more signaling links, iii) process the content and signaling information associated with the plurality of calls based on the state information; and iv) transmit said content information to a destination over the active communication link based on the signaling information processed by the first processor module; and a second processor module, said second processor module of said media gateway in communication with the receiver module and the first processor module, the second processor module being coupled to the packet-based network by a standby communication link and being configured to i) receive in parallel with the first processor module data associated with the plurality of calls from the receiver, ii) process at least a portion of the signaling information associated with the plurality of calls asynchronously and in parallel with the processing of the signaling information in the first processor module, iii) determine state information about the one or more signaling links and to synchronize the determined state information with the state information maintained in the first processor, iv) maintain the synchronized state information, and v) maintain the content information associated with the plurality of calls.
