Abstract
Methods, media gateways, and computer program products are described associated with call redundancy for a packet-based network. The described call redundancy involves a receiver module in communication with the packet-based network adapted to receive or transmit data associated with a plurality of calls from one or more signaling links. The data includes signaling information based on a publicly-switched telephone network (“PSTN”) standard. A first processor module is in communication with the receiver module and is adapted to process the data associated with the plurality of calls. A second processor module is in communication with the receiver module and the first processor module. The second processor module is adapted to receive at least a portion of the data associated with the plurality of calls. At least a portion of data maintained on the second processor module is synchronized with the corresponding data processed by the first processor module.
