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.
