ABSTRACT:
A conference bridge adapter for processing data carried on a media path between, on the one hand, a conference bridge operative to communicate composite packets carrying media information and auxiliary information pertaining to the media information and, on the other hand, an endpoint characterized by an inability to exchange composite packets with the conference bridge. In one direction, a stream of composite packets is received from the bridge. An output media stream without auxiliary information is generated from the media information in each received composite packet. In the opposite direction, a stream of packets carrying only media information is received from the endpoint. Auxiliary information is derived from the media information and a stream of composite packets is generated by combining the media information and the auxiliary information. Thus, a media conference can be established between seemingly incompatible network elements.
