Patent ID: 8054827

Claim:
A method comprising: 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 being based on a publicly-switched telephone network (“PSTN”) standard and including a first portion associated with a lower portion of a MTP2 layer and a second portion associated with an upper portion of the MTP2 layer; processing, at the media gateway using a common processor that includes a digital signal processor module in communication with a general-purpose processor module, i) the first portion of the signaling information associated with the lower portion of the MTP2 layer using the digital signal processor module and ii) the second portion of the signaling information associated with the upper portion of the MTP2 layer using the general-purpose processor module; terminating, at the media gateway, the signaling information without forwarding the signaling information to a destination; and transmitting, by the media gateway, the content information to the destination based on the signaling information.
