For example, when an H.320 ISDN terminal wants to participate in a multipoint
conference with H.323 IP endpoints, the H.320 ISDN terminal can either join
the multipoint conference by dialing to the Gateway, or be invited into the
conference by one of the participating IP endpoints. In either case, the Gateway
connects the ISDN terminal to the
