    Abstract: A multi-network exchange system has a first type network (PSTN) and a second type network (Internet) and a multi-network exchange bridge in communication with the first and second type networks for the transfer of electronic information signals (telephone calls) between the first and second type networks. The multi-network exchange bridge apparatus facilitates transfer of electronic information signals to a portable access device or a gateway portal in communication with a node of one of second type networks from the first network. The multi-network exchange bridge has at least one multi-network instantiation device that enables the portable access device to function as a remote extension of the multi-network exchange bridge.
