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.

Abstract: Methods, systems, and computer program products are described associated with publicly-switched telephone network (“PSTN”) signaling at a media gateway for a packet-based network. The described signaling involves receiving, at a media gateway in communication with a packet-based network, signaling information and content information associated with one or more calls. The signaling information is based on a PSTN standard. At least a portion of both the signaling information and the content information is processed at the media gateway using a common processor. At least a portion of the content information is transmitted to a destination based on at least a portion of the signaling information.
