Abstract

A system and method for a packet VRU which directly utilize packet network protocols, such as those of the H.323 standard, to provide enhanced services via a packet network. The packet VRU generally operates within the packet network and is not required to provide data format translation or multiple device-type access. In a preferred embodiment of the present invention, the packet VRU redirects the media stream from a source so that it is sent directly to a destination, instead of passing through the packet VRU. Alternatively, if the packet VRU must perform processing on the message contents, the packets may be sent to both the destination and to the packet VRU. The packet VRU may still retain call control over the media streams by maintaining the signaling and user input components of the call.
