Abstract
The present invention enables packet-switched network providers, e.g., VoIP network providers, to use commonly deployed components and capabilities to support surveillance services, e.g., CALEA services. Specifically, signaling and media streams that flow through Border Elements can be forked and simultaneously redirected to a surveillance server, a CALEA Server in addition to the terminating endpoint. Additionally, a Media Server (MS) can unobtrusively join a third leg to a communication media path between the CALEA Server and the two, calling party and called party, endpoints. A CALEA Server provides the ability to identify and collect content of voice telephone calls traversing the VoIP Network, as mandated by the Communications Assistance for Law Enforcement Act.
